How to Make a Cup Anemometer (DIY Paper Cup Anemometer) – Video

An anemometer measures wind speed and making a DIY anemometer out of cups is a great school science project. In this article, we’re going to give you a step by step guide for how to make an anemometer with cups and straws and answer some questions you might have.

How to Make a Cup Anemometer (DIY Paper Cup Anemometer)

How to build a cup anemometer

This straightforward video shows you how to make an anemometer step by step. Below we’re going to repeat the steps and give you a little more detail on some of them. First, here’s what you will need:

Anemometer Ingredients

How to build an anemometer at home – Step by step guide

Step 1 – Use the sharpened pencil to poke a hole in the bottom of one of your dixie cups or another type of paper cup if you’re using easter egg cups for your DIY anemometer. Then use your hole-punch to punch two sets of 2 holes (four holes total) so that each hole is perpendicular to another hole. One set of holes should be closer to the top rim of the cup, and the other set of aligned holes should be lower down.

Step 6 – The cups should twirl in the air easily. To finish your anemometer, place the pencil into your empty plastic soda bottle for a base. You can use stickers or a marker to make an X on one of the four rotating cups which will make counting revolutions easier (it will be obvious how many times the red dot or X has turned around).

How to use your cup anemometer to measure wind speed

Have one person look at a stopwatch to see exactly how long ten seconds is. Use the following chart below to calculate roughly how fast the wind is blowing.

Alternatively you can “calibrate” your anemometer by driving exactly 10 miles per hour and seeing how many times your cups rotate when held out the window. However many revolutions are equivalent to wind blowing 10 miles per hour (assuming there is no additional wind blowing). Obviously you don’t want to be driving and sticking your arm out the window counting anemometer cup revolutions so you’ll need two people for this step.

Frequently asked questions about cup counter anemometers

How does a cup anemometer work?

Cup anemometers are used by professionals to gauge wind speed. Normally anemometers will have built in computers that calculate how many revolutions they make per minute (or every 10 seconds or every 30 seconds, depending on how the computer is set up). The number of times that the wind pushes the cups around in a circle is then translated into the wind speed by the anemometer’s calculator into a unit like miles per hour, meters per second or whatever unit is desired. The more times the cups turn around in a circle, the faster the wind is blowing.

What is the difference between a 3 cup anemometer and a 4 cup anemometer?

Three cup anemometers are similar to four cup anemometers, they just simply have one less wind cup. For the purposes of this article about how to make an easy anemometer, we’re making a four cup model since that’s easier to make. Four cup models are also more common these days than 3 cup or 2 cup anemometers.

What is the cup anemometer working principle?

Cup anemometers feature a rotating array of wind cups that rotate as the wind blows. The faster the wind is blowing, the faster the cups will rotate. By measuring the number of cup rotations within a period of time (for instance within 30 seconds), we can calculate how fast the wind is blowing.

What other types of anemometers are there besides cup anemometers?

While this article is about how to make a kid friendly anemometer out of cups, there are several other types of wind guage instruments. Some examples include: hot wire anemometers (which measure how quickly a heated wire cools down in the breeze), ultrasonic anemometers (which transmit a sound signal to a reciever, measuring wind speed off of how long it takes to send it), and vane anemometers (which work on the cup principle but instead of rotating cups they have flat blades like a fan).

I don’t understand the instructions for how to make anemometer at home

Watch the “how to make anemometer video” at the top of this article for more information about how to build an anemometer out of cups for a school project.

I don’t want to use dixie cups, what else can I use for my homemade DIY anemometer cups?

Here are some ideas for how to make an anemometer with cups– using things other than dixie cups:

  • Colorful plastic egg shells – separated in half
  • Ping pong balls – sawed in half
  • Paper cups or condiment cups
  • Plastic soda bottles – sawed in half

Terms Defined / Anemometer Vocabulary

Anemometer An anemometer is a device that measures the speed of the wind. Anemometers are used by many professionals who work in the wind energy field as well as meteorologists/weather scientists, hobbyists and others. Different anemometers measure wind speed differently, depending on how they’re designed.

Cup anemometer A cup anemometer is a specific type of anemometer that measure wind speed by counting the number of rotations that a set of cups makes when the wind blows. Cup anemometers can be manual like the types of cup anemometers made of paper cups for science projects, or they can be electronic. Sophisticated cup anemometers can calculate the wind speed in units like miles per hour, meters per second or Knots (a naval unit of measurement for sailing). Simply put, the cup anemometer definition is: a wind speed gauge that uses rotating cups to measure wind speed.

Wind energy Wind energy is power created by the wind blowing.

Windmill A windmill harvests the power of the wind and translates it into energy. Early windmills pumped water or milled grains but today modern wind turbines generate electricity.

Wind farm A wind farm is an array of wind turbines in a windy area that all work together to harvest a large amount of wind power.

Wind/weather vane A weather vane or wind vane is a flat instrument which rotates. Depending on which direction it’s pointing, it will tell you which direction the wind is blowing in.

All About Anemometers: What They Are, How They’re Used & Much More

In this mega-FAQ we’re going to explain to you what anemometers are, who uses them, how they work, who invented them, and much, much more. Let’s begin!

What is an anemometer?

The simple answer to this question is an anemometer is a wind speed meter. There are different types of anemometers and they work in different ways but all anemometers have ways of measuring wind speed. Here are a few examples of what different types of anemometers look like (click any image to enlarge it in a new window).

As you can see, anemometers come in all sorts of shapes and sizes. Some are portable handheld anemometers and others are built in and affixed to buildings as a part of weather stations.

What is an anemometer used for?

what is an anemometer used for

An anemometer is for measuring wind speed. Some anemometers are built into larger, more complex weather stations which contain various other instruments and can provide weather forecasts based on a combination of all the data.

For instance an anemometer may be used to measure how windy it is before you go sailing on a sailboat. An air conditioning repair technician might use an anemometer to measure the output of a unit they are troubleshooting. A meteorologist might use anemometer data in their forecasts. A professional sports shooter might use an anemometer to calculate crosswind so they can compensate and hit a target from many hundreds of feet away. Storm chasers and weather hobbyists might use anemometers to understand how fast the wind is blowing. A wind turbine surveyor may use a handheld portable anemometer to determine if a particular area would be a good location to harvest wind power from.

What is an anemometer and how does it work?

An anemometer measures wind speed. Most anemometers work by counting the number of revolutions that their circular array of cups or windmill or blades make within a period of time (say, a 10 second interval) to see how fast the wind is blowing. It can then translate that measurement into a calculation of wind speed in units like miles per hour, kilometers per hour, meters per second or in the case of sailing applications, Knots.

What is an anemometer unit of measurement?

Anemometers measure wind speed in a variety of units. Generally speaking, the more expensive and sophisticated the anemometer is, the more units of measurement it will offer. Anemometer units of measurement may include:

  • MPH (miles per hour)
  • Km/H (kilometers per hour)
  • Knots (for sailing or windsurfing)
  • Feet per minute
  • Meters per second
  • Beaufort scale (a specialized wind speed measurement – read more on Wikipedia)

How does an anemometer work?

Most anemometers fall into one of two general categories: vane (or turbine) anemometers and cup anemometers. In both cases as the wind blows through them and moves their parts around in a circle, they count the number of revolutions per second (or per minute or per 30 seconds or whatever time period). By evaluating the speed of the rotations, the anemometer is able to calculate the wind speed in a common unit of measurement like miles or kilometers per hour.

There is also a third type of anemometer, a hot wire anemometer, which heats a component and then measures how quickly the component cools down (giving a reading of how fast the wind is blowing to cool it). A fourth, more rare type of anemometer is an ultrasonic anemometer, which we will explain below.

What is an ultrasonic anemometer and how do ultrasonic anemometers work?

Ultrasonic anemometers measure wind speed. They do this by sending a sound pulse back and forth from a transmitter to a receiver over a span of a few inches to calculate the speed of the wind blowing in between the two sensors. Ultrasonic anemometers are extremely specialized devices and they tend to be much more expensive than typical anemometers in the more common vane, cup or hot-wire types.

How much do anemometers cost?

Anemometers cost less money than you might think. You can get a portable handheld anemometer for under $20. Of course more sophisticated anemometers with lots of additional features and sensors can cost hundreds of dollars. (See our related article: The best wind meters for long range shooting for some more examples of anemometer cost range.)

How to use an anemometer / how to read an anemometer

In the case of electronic anemometers (most of them), normally you’ll just to turn on the unit and watch as it displays the current wind speed. You may decide to change the mode to view the wind speed in a different unit of measurement (i.e. kilometers per hour instead of miles per hour). In the case of manual cup anemometers for science class projects you’ll need to count the number of revolutions the cups make in a minute long period to calculate the wind speed.

How do you pronounce “anemometer”?

This video shows you how to pronounce anemometer:


How do cup anemometers work?

A cup anemometer (like the ones seen above– click on an image to open it larger in a new window) counts the number of times that the wind revolves a set of cups around in a circle over a period of time to calculate wind speed. At their most simple, cup anemometers consist of a stick of some kind that holds an array of 2, 3, or 4 wind cups which rotate. High school students will sometimes build anemometers or use simple non-electronic cup anemometers like the one below to manually count rotations over a period of 1 minute or 30 seconds to calculate wind speed.

How accurate is an anemometer?

Different anemometers will have different levels of accuracy. Generally speaking the more expensive the unit the more accurate you can expect it to be (no surprise there!). A common handheld decent quality anemometer accuracy range is within ±3%. This means that if the wind is blowing at 20 miles per hour, the unit might register anywhere between 19.4 mph and 20.6 mph, so fairly accurate for most purposes. Specialized scientific anemometers such as ultrasonic anemometers may have even higher accuracy rates.

Where is an anemometer placed?

Anemometers come in two varieties; those that are handheld and portable and those that are mounted in a single fixed location. For the most accurate readings, anemometers are best placed in locations that are unencumbered by obstacles so you can get a wind speed reading that isn’t blocked by trees/buildings/etc. For instance, the absolute worst spot for an anemometer would be directly next to a building or wall. Anemometers are sometimes mounted atop poles in the middle of yards, on top of buildings or in wide open spaces.

Does anemometer measure wind direction?

Anemometers measure wind speed. Some anemometers will also calculate the direction that the wind is blowing. These anemometers will often rotate or have an additional vane attachment that detects the wind direction. So to answer the question “Does anemometer measure wind direction?” we can say that most measure direction (they measure speed only), don’t but some higher end, more expensive models measure both speed and direction.

How is an anemometer different from a windsock?

Windsocks are a very simple way to gauge “is the wind blowing?” and “is the wind blowing fast or slow?” at a glance. But anemometers are very sophisticated instruments that can tell you precisely how fast or slow the wind is blowing, and sometimes even which direction the wind is blowing from. Anemometers will sometimes also be built into a feature-rich weather station which measures other factors like temperature, humidity and barometric pressure.

what does an anemometer look like / how does an anemometer look?

Here are some examples of what different types of anemometers (wind speed meters) look like. Click on any image to open it in a new tab and learn more about it.

How is an anemometer used? How is an anemometer helpful?

Anemometers, which measure wind speed, are used by many people for a variety of purposes. Knowing the wind speed is helpful to sailors, windsurfers, air conditioning repair technicians, professional sports shooters who need to know crosswind, meteorologists, and weather enthusiasts. Sometimes anemometers are built into sophisticated pieces of equipment with many other sensors called personal weather stations which are used by people who live in remote areas or microclimates where traditional weather forecasts are inaccurate.

How do anemometers work? How do anemometers measure wind speed?

Most anemometers have some sort of moving part which rotates or cycles in the wind so when the wind blows faster it will rotate faster. The anemometer’s computer counts the number of revolutions per second or minute (or whatever interval) and then figures out what the speed of the wind is in miles per hour, meters per second or whichever unit it’s set up to read. If you’re interested in learning more about how anemometers calculate wind speed, read on at Wikipedia.

Who invented the anemometer first?

Italian Renaissance man Leon Battista Alberti is credited with inventing the first anemometer, or wind speed meter, around the year 1450. Later in 1846 the English astronomer Thomas Romney Robinson invented the first cup anemometer. You can learn more about the history of the anemometer on Wikipedia.

Who invented the hot wire anemometer?

The first constant-current wire anemometer for practical use was created in 1909 by Russian scientist Dimitri Riabouchinsky (more info).

What does an anemometer and weather vane measure?

An anemometer measures wind speed. A weather vane measures the direction that the wind is blowing (for example, north-south or east-west).

How does an anemometer help meteorologist / why is a anemometer important to weather forecasting?

Basically what anemometers do is they tell you how fast the wind is blowing. If you’re interested in how an anemometer is used to measure weather, check out this answer from an engineer:

Meteorologists use anemometers to measure wind speed. Wind speed is obviously a weather feature reported in itself, but meteorologists use the data for other reasons as well. Gathering wind speed and direction at many locations and altitudes allows meteorologists to create the weather maps used to predict weather across the world several days ahead.

How does anemometer indicate the speed of the wind?

Most anemometers count the rotation of a series of cups or vanes to see how fast the wind is blowing. The faster the wind is, the faster the cups will rotate in the wind (or the faster its turbine will rotate). That speed is then calculated by the anemometer and displayed in a unit like miles per hour or meters per second on the display. In the case of an old fashioned manual cup anemometer, high school science students will often count the number of rotations and calculate how fast the wind is blowing based on that. See below for a simple cup anemometer example:

What is an anemometer used for in science?

What does an anemometer tell us? It tells us how fast the wind is blowing. This may be useful for a variety of different scientists. For instance, meteorologists use anemometers to calculate wind patterns. Renewable energy scientists and engineers may use handheld anemometers to figure out whether a particular place is a good spot for a wind turbine. Other scientists testing lab equipment may have different specialized uses for anemometers. So, what does an anemometer help scientists measure? Wind speed (or air flow, when indoors).

An anemometer is a gauge used for recording the speed of what?

Anemometers measure wind speed. Some very sophisticated anemometers and weather stations can also calculate the direction that the wind is blowing in, in addition to the speed at which it’s blowing.

How big is an anemometer?

Some anemometers are portable and can be held in your hand and stowed in a pocket. Others are part of a larger weather station and can be mounted on the rooftops of buildings or on poles in big open fields. The size of anemometers really varries widely depending on how it’s meant to be used.

How is an anemometer different from a weather vane?

A weather vane measures the direction that the wind is blowing. You frequently see them atop old houses or sometimes in people’s yards, ornamentally. An anemometer on the other hand is usually an electric device that measures the speed that the wind is blowing, based off of how fast a set of cups or a turbine is rotating. Anemometers come in both handheld and stationary mounted varieties. Some anemometers measure the wind direction as the speed, while others measure only the wind force.

Kestrel makes two models of long range shooting wind meters with applied ballistics: the Kestrel Elite and the Kestrel Sportsman. The Elite model has more functions and more memory for custom data, whereas the Sportsman has less (but also costs less).

What is the best wind meter for shooting?

On this page we’ve laid out several long range shooting wind meter options, but if we had to pick the absolute 100% most fully functioning one, it would have to be the Kestrel Elite Weather Meter with Applied Ballistics. Both this wind speed gauge’s features and its reputation as an industry standard speak for itself when it comes to wind meter shooting excellence. When you factor in budget however, there are plenty of other candidates for the best wind meter for long range shooting, which we’ve listed above.

What is the difference between the Kestrel Sportsman vs Elite for long range shooting?

Generally speaking the Kestrel Elite model has more memory banks for additional custom guns than the Kestrel Sportsman model has, and a more detailed ballistics display. Because the Kestrel ballistics solver calculates each combo of a gun and a bullet separately, having more data banks to store different combinations is quite useful (you can always overwrite on top of the memory banks but inputting the data is a bit cumbersome and slow).

Is it worth paying extra for a Bluetooth enabled Kestrel wind meter for shooting?

We’d say yes. If you’re going to be using an anemometer for long range shooting frequently or with a number of different gun/bullet combinations, it’s especially worthwhile. Not only does this mean you’re able to input combinations of bullets and guns more easily with a full sized phone keyboard (instead of the button combination on the Kestrel unit), it also has a nice display with additional information. If you do plan on using the iPhone or Android app with your Kestrel for long range shooting purposes, we recommend getting a wind vane and mount with it because holding both devices at once is awkward. Note that the app can store more rifle/load combinations than the Kestrel unit can, since your phone has more storage.

5 Best Weather Alert Radios for Storm Warnings

If you live in an area where extreme weather, thunderstorms, or tornadoes are common, you know how important advance storm warnings are for the safety of your family or home. One of the best ways to receive weather alerts in real-time is by using a weather alert radio. There are a variety of weather emergency radios available, whether you just want something for your home or something easy to use on the road. We’ve examined the top-rated weather alert radios available to find the best options. Check out our report on the best storm radios below.

Best Emergency Radio Reviews

Midland NOAA Weather and All Hazard Public Alert Certified Radio

The US weather experts at NOAA issue location-specific weather alerts using a protocol called the S.A.M.E. code and you can set this storm radio to receive only alerts affecting your area (it’s user-programmable to include a larger region too; up to 25 counties!). You can set it to use whichever of three alert systems you prefer: a 90-decibel siren, a voice alert or a flashing LED light. It also works with three AA batteries as a backup in case your home loses power during a storm.

This weather radio works in both the US and Canada and provides safety alerts in three languages (English, Spanish and French). The Midland WR120 (this model) is one of the top-rated weather alert radios, after having gotten a massive number of positive reviews. It also works as an alarm clock.

RunningSnail Solar Crank NOAA Weather Radio For Emergency

Here’s another one of the best weather radios that has a couple of unique features. It receives warnings on 7 NOAA weather channels and also receives AM and FM radio. It also has a built-in flashlight and LED reading lamp and is waterproofed enough to work outdoors during rainy weather, making it a great all-purpose and weather radio for camping trips.

Plus, it can be charged with USB power from a computer or USB power brick (like a cell phone charger), or AAA batteries or a hand crank or solar power with its built-in solar panel for use outdoors! The built-in solar panel is also adjustable so you can set an appropriate angle for use. This alone makes it one of the best emergency weather radio for preppers.

Midland Portable Emergency Weather Radio with S.A.M.E.

The Midland Portable Emergency Weather Radio is a great hybrid device that can either sit on a flat surface in its charging cradle or be carried around handheld on battery power. It uses NOAA’s SAME weather alert technology to give you only the weather alerts that are useful to your local area and it can be customized for up to 9 counties at once. It also uses Midland’s Weather Scan technology, which lets you scan the local area and latch on to whatever the strongest NOAA channel is automatically.

The Midland HH54VP2 receives information on nearby hurricanes, tornadoes, floods, ice storms and other weather events as well as civil emergency information about Amber Alerts, fires, and chemical spills. The clear LED screen is backlit for use in the dark. This is one of the best weather alert radios for handheld use.

Kaito Emergency AM/FM/SW/NOAA Weather Alert Radio

The Kaito KA500 storm radio can be powered in six different ways: by 3 AA batteries, a built-in angle-adjustable solar panel, a hand crank, by USB from a laptop or cell phone charger, by a rechargeable battery pack or an AC/DC wall adapter (not included).

The Kaito emergency weather radio can receive AM/FM weather as well as NOAA weather alerts and it also functions as a flashlight and reading lamp. It even can charge a cell phone with a USB power output port. This model also has a blinking red light mode which can serve as an emergency beacon. Telescopic antenna extends up to 14 and a half inches. Water-resistant and comes in several different colors.

American Red Cross FRX3 Hand Crank NOAA AM/FM Weather Alert Radio with Smartphone Charger

This emergency weather radio, certified by the American Red Cross, combines several features into a neat package, complete with carrying handle and bright red color. It receives AM/FM radio as well as all 7 NOAA weather stations (or Environment Canada), plus it has an alert function for extreme weather warnings. It also can charge your cell phone via USB and has a flashlight on its side. Powered by either 3 AAA batteries, a built-in solar panel, the built-in hand crank or a computer or cell phone charger via USB. This weather radio is smaller than it looks in the product photos but it also has a blinking red light for beacon mode to find it in the dark.

Frequently asked questions about storm radios

Can I tune a storm radio or emergency radio to a normal AM/FM radio station? Not every emergency radio has this feature; some weather radios only tune to weather radio stations. But in our weather alert radios reviews above we’ve included whether or not each model allows for AM/FM tuning. If in doubt, check the product listings themselves.

What are the important features to look for in a weather alert radio? It depends on what you’re using it for but we generally recommend looking for a weather radio that has multiple ways to power or charge it just in case you lose power. Many weather radios have the ability to charge from a built-in hand crank and some may even include a built-in solar panel (though in stormy weather this won’t be of much use). For some, it may be important to get a handheld weather radio which can fit into a pocket. We also recommend considering getting an emergency weather radio that has a way to charge a cell phone, as many of the models listed in these reviews have.

What kind of information will I get using a weather alert radio? A weather radio using the NOAA S.A.M.E. weather protocol alert system will broadcast alerts tailored to your specific area using a series of county-codes (many weather radios let you program in a range of county codes that are relevant to your area). Weather radios capable of receiving the 7 channels of NOAA broadcasts will also receive weather alerts. Some weather radios will also give you access to civil emergency information like Amber Alerts and information about other local emergencies such as chemical spills. Still, other weather radios will also have AM/FM tuning for receiving normal radio broadcasts.

Factors to consider when choosing a handheld anemometer or handheld weather station

Does this anemometer measure more than just wind speed?

The most basic handheld anemometer will measure wind speed, temperature and probably nothing else. If your needs are limited to just that, then you can probably get away with a basic entry-level cheap handheld wind meter. But if there’s a chance you might need some more weather sensors such as barometric pressure or dew-point, then you might be more interested in a fully fledged portable weather station. Still other more advanced portable weather stations can offer analytical information like heat stress index, Beaufort scale equivalents, or windchill based on combining multiple measurements into one.

Will I be using this mobile anemometer near water or in rain?

Some handheld anemometers are waterproof and others even float. If you’re planning on bringing your wind speed meter on a boat or in adverse weather conditions, we recommend getting a portable anemometer that’s designed for that (such as the floating and waterproof Kestrel models listed on this page).

Do I need a detached instrument or is an all-integrated wind speed meter okay?

Some users who are interested in extremely precise humidity or temperature measurements will want to consider an anemometer with a jackknife design such as the Ambient Weather WM-5 listed on this page which has a flip-out display cover which you can hold on to instead of the unit itself so as to avoid from influencing the data collection with hand-sweat or body heat.

What type of weather conditions will I be using this handheld anemometer in?

If you’re a storm chaser that regularly finds themselves in high wind conditions then you might have more rugged needs than, say, an HVAC technician. Some anemometers are more rugged than others and can measure wind velocity up to almost a hundred miles per hour. Generally speaking the more expensive the anemometer, the faster the wind speed it should be able to read.

What is the price of this handheld anemometer?

Price is often a factor and the price range of handheld wind speed meters and portable weather stations ranges from a few dollars to several hundred. If you are planning on purchasing additional accessories such as tripods or other gear to use with your portable wind speed meter you’ll want to be sure to factor that price into the total purchase price of your system. Ultimately the best handheld anemometer is the one that’s right for you.

Do I need/want smartphone app compatibility for my handheld wind speed meter?

Some higher end wind speed meters such as the Kestrel models or WeatherFlow ones on this list offer the ability to connect your wind speed meter or weather station to your cell phone via iPhone or Android apps which you can download to provide in depth analysis of your hyperlocal weather conditions.

This Bluetooth connectivity can be useful for looking back at stored historical data (i.e. recognizing that a particular wind speed is the highest ever recorded, or what’s “normal” wind speed for a ventilator system). Handheld wind speed meters that work with your phone can also sometimes hook up to other third party apps like ballistics apps for shooters.

What are handheld weather stations or handheld anemometers used for?

There are a number of things that people use handheld anemometers, pocket weather stations and portable wind speed meters for. Generally speaking, these are grouped into several different categories by use type:

Pocket wind speed meters for firefighters – In some places wind speed and directionality can be a matter of life and death. It’s hard to think of a more critical use case for accurate wind speed meters or anemometers than firefighters battling a forest fire. Firefighters may use pocket weather stations to predict how conditions may change that impact the way that they fight wildfires as well as get a sense of where they may be able to safely be located while they’re fighting wide ranging fires.

As one firefighter says in the video above: “The reason [wind is] important to us, fires can create their own wind but they’re also driven by the wind that goes on within the weather. Increased winds will increase the veracity of the fire, changes in wind direction will change the direction that the fire’s going, so those are things that are important for us to know when we come on the scene and monitor for changes during event.” Relative humidity and temperature are also important weather factors for firefighters to monitor because humidity affects how quick nearby tinder is to catch fire.

Handheld anemometers for HVAC professionals – Contractors installing or maintaining heating, cooling and air conditioning units often find handheld anemometers useful because they’re a convenient pocket sized way to gauge how fast air is blowing, and whether a unit is faulty or not without having to rely on what it “feels” like.

Portable weather stations for hikers & backpackers – If you’re hiking in a microclimate or out in the middle of nowhere you may not have access to reliable weather data, especially at high altitudes. Carrying a pocket weather station with you can help produce accurate hyperlocal weather forecasts which can determine whether it’s important to seek shelter in the case of adverse weather conditions.

Handheld wind speed meters for model plane enthusiasts – Although pilots of large aircraft can usually rely on other sources of weather data, model plane and drone pilots often find handheld wind speed and direction meters invaluable when determining their own hyper-local flying conditions.

anemometers and wind speed meters for sailing

Portable anemometers for sailing – Large sailboats sometimes have anemometers (wind speed and direction meters) built-in but smaller boats don’t have these and it’s often handy to be able to check wind speed with a handheld device.

Anemometers for sports shooters & hunters – For sports shooters, wind speed and directional information can be quite useful to boost the accuracy of their shots. While hunters are interested in accuracy they may also be even more interested in the direction of the wind for scent purposes (hunting upwind, etc). Read more about the effect of wind speed and direction as well as scents in hunting in this article.

Weather stations & barometric pressure meters for fishing – Fishers also sometimes use pocket weather stations to measure barometric pressure which fish react to. In high or low barometric pressure environments fish swim slowly in deeper waters, while in falling pressure environments fish are more likely to be swimming near the surface and be ready to bite at any opportunity.

Wind speed meters for agricultural users – Farmers sometimes need to measure barn ventilation as well as temperature conditions for livestock purposes and so handheld portable wind speed meters are useful for them as well.

Wind speed meters for wind power professionals – People working in the rapidly expanding wind power energy sector often use handheld anemometers to measure wind speed at locations they’re considering putting in new wind turbines or windmills, as well as for measuring data when doing maintenance checkups to existing wind power sites.

Coaches and trainers who need handheld heat stress meters – Some coaches working with athletes outdoors during summer or winter may want to use a wind speed meter that has a built in heat stress meter to monitor weather conditions by synthesizing a combination of temperature, wind speed as well as humidity. This is useful to make sure athletes don’t over-exert themselves in challenging weather conditions while training. Some handheld wind speed meters such as Kestrel models offer this feature.

Pocket weather stations for storm chasers – Storm chasing is one of those hobbies that’s gaining popularity due to both cheaper equipment and the effects of climate change producing more extreme weather variations. Storm chasers often use pocket anemometers in conjunction with other gear to monitor current weather conditions and trends. Pocket anemometers allow storm chasers to measure weather conditions surrounding extreme weather events without fragile equipment, since most of these small devices are rugged and many are weatherproof and come with lanyards or hand straps.

Pocket wind speed meters for EMTs & public safety workers – Portable wind speed meters are also useful for emergency medical technicians (EMTs) and also public safety workers dealing with avalanche control, smoke coordination, forensics, hazmat/biohazard remediation, K9 handlers, dive rescue workers, search and rescue, and more.

Pocket weather stations for Weather enthusiasts – The weather hobbyist community is growing and as weather station gear has gotten more both more portable and more affordable, some weather enthusiasts are choosing to buy their own portable weather stations. Weather reports generally offer forecasts for a large area– sometimes many square miles, and will never be as precise as the information you can get from your own handheld weather station.

Of course there are plenty of other reasons why a person might want a handheld weather station that aren’t related to any of the use cases listed above. Whatever the reason that you’re looking to buy a pocket anemometer we hope you find this article useful.

Frequently asked questions about handheld anemometers

What is an anemometer?

An anemometer is a wind speed meter that captures measurements on air velocity. To learn more about these devices, read our article titled What is an Anemometer and What is it Used For?

Some anemometers are more complicated and offer other advanced features like humidity, temperature and barometric pressure. These are sometimes referred to as personal weather stations.

Are there other types of anemometers besides the fan/vane anemometers listed in this article?

Yes, another popular anemometer type that sometimes comes in a handheld version is a cup anemometer. Read our article on those for more: The Best Cup Anemometers & How Wind Cups Work

How do anemometers work?

The anemometers on this list have fans or “vanes” which rotate at a speed based on the wind velocity. The devices then measure how fast the wind vane or fan is turning and then translate that into the speed of the wind in units such as miles per hour, meters per second, knots, or other units.

What is a wireless anemometer? What are wireless wind speed meters used for?

An anemometer measures the wind speed in a given area and a wireless anemometer measures wind speed and transmits it to a base station with a screen where you can view that information remotely.

One common use case for wireless anemometers is when a person wants to be able to tell how windy it is outdoors without going outside, and they don’t want to have to fumble with cables or wires to connect their wind speed meter (anemometer) with an LCD display. Often times the cables that come with even the best cup anemometers are too short and a hassle to deal with.

Factors to consider when buying a rotating cup anemometer

What is the wireless range of this anemometer?

Most wireless anemometers have a range of a few hundred feet. Since they commonly broadcast on the 915 MHz RF wireless transmission frequency, 330 feet is a very common range limit for these units. A few professional grade wireless anemometers have ranges of up to around 1000 feet.

Are there any drawbacks to making an anemometer wireless?

It’s not easy these days to find a wireless wind meter that only measures the speed of wind and not other factors like wind direction, temperature and other weather factors. These days it’s much more common to find a wind speed meter (anemometer) that’s bundled as part of a larger personal weather station kit. This might have possible downsides like increased cost. But we’d argue that in many cases it’s handy to be able to have all that extra data at your fingertips without needing to venture outside– even if all you think you initially are interested in is wind speed.

How many indoor LCD base stations does this come with? What are the base station’s features?

Some LCD base stations are easier to read than others, and different wireless anemometers will display different types of data on their screens. Be sure to examine the example display readout of any wireless wind speed meter that you are considering to make sure you’re happy with the display since that’s what you’re actually going to be relying on for information. Some LCD displays are in color, some are larger than others, and some distill all their information into a personalized forward looking 12 or 24 hour weather forecast (like “showers likely”).

Can this wireless anemometer connect to my computer? Does it have a mobile phone app that I can check from anywhere?

Some personal weather stations allow you to connect their base stations to a computer to sync weather data like wind speed, temperatures and so on for analysis. This can be useful if you’re tech savvy and some weather stations eve allow you to upload your data automatically to websites like Weather Underground, where thousands of weather enthusiasts contribute data to crowdsource a very accurate view of global weather. Some wireless anemometers also come with a mobile phone app that will let you check weather conditions at home even while you’re away.

It’s worth keeping in mind that all of the weather stations in this article only work with PCs and many will only upload data as long as they are plugged into your computer and it’s on and connected to the internet. One of the units in this list, the Ambient Weather unit does not need to be connected to a PC, it comes with a special wireless relay device of its own that uploads information to the internet for you without needing to be plugged into a computer that’s on.

What type of batteries does this potential wireless wind speed meter use?

Before you buy a wireless wind speed meter, be sure to check to see what kind of batteries it accepts and what the approximate battery life is expected to be. You probably won’t want to be changing the batteries every month for example. Many of the units featured on this page have a battery life ranging from many months to even a couple of years on standard AA batteries.

What is a cup anemometer?

Cup anemometer definition: Anemometers measure wind speed, and a cup anemometer is specific type of wind speed gauge that measures the speed of wind or air flow based on how quickly a set of cups turns around in a circle.

Cup anemometers are one of the older types of anemometers or wind meters and they’re they’re still popular today among weather hobbyists and professionals measuring wind and weather. Cup anemometers are generally pretty accurate and they come in a few different varieties with the major difference being how many different cups they have (two, three or four) and whether or not they electronically count the revolutions per minute or whether you need to count them manually to measure wind speed. The cup anemometers that are manual and do not automatically count revolutions are generally meant for student use and not professional use. Often the manual count anemometers will have one cup that is a different color to help make it easier to count the number of revolutions the wind cups make per minute.

Cup anemometers will also sometimes come as part of a larger weather station with additional instruments. They also come in different form factors: some are designed to be mounted on the outside of buildings, others work well on top of a car, and still others are meant for handheld portable use.

Common wind cup anemometer users: home weather hobbyists, storm chasers/storm spotters, HVAC contractors, wind power professionals, windsurfers, sailboat owners.

How does a cup anemometer work?

As the wind is caught in each cup on a wind cup anemometer, it pushes the cup to rotate and catches the next cup in its path, making the cup spin. The number of revolutions per minute will determine how fast or strong the wind is blowing. Some wind cup meters require you to manually count the revolutions per minute to discover the wind speed; other wind cup speed meters will measure the wind speed digitally and calculate it for you by counting the rotations on an internal computer.

A wind cup anemometer is a relatively basic but still fairly accurate wind instrument from a scientific point of view. They are in common use at weather stations around the world and points of interest where wind velocity is extremely important to understand such as airports. They are also used by wind power professionals who are evaluating sites for potential turbine installation.

Factors to consider when buying a rotating cup anemometer

Does this cup anemometer have a digital readout or will I need to manually count revolutions? This is a pretty obvious question and in most cases most people will require an anemometer with a wind calculator built in. One exception may be science teachers or those looking for a weather related gift for a child.

Is this cup anemometer handheld or mount-able? Some cup wind meters are meant to be mounted on cars or buildings or poles, and others can be brought with you wherever you go.

Does this mountable anemometer have a wired or wireless display? If you’re looking to use an anemometer mounted on your vehicle or outside of your home you may be especially interested in getting a wireless anemometer with a decent range to it so you can measure the wind speed without having to have a cable hooked to your device outdoors. Some rotating cup anemometers have wireless displays that can be placed hundreds of feet away and others require a cable to go from the wind cups to the display indoors. Regardless of whether or not your anemometer is wired or wireless, you’ll want to check the maximum range or cable length of the display you’re considering.

How many cups does this anemometer have? Cup anemometers come with a variety of different cup counts: some are 2 cup anemometers, others are 3 cup anemometers and still others have 4 cups.

Do I want a cup type anemometer that has logging built in? If you’re interested in logging wind velocity, you may be particularly interested in a cup anemometer which works with your smartphone so the wind speeds you measure can be logged with time and location.

Do I only care about measuring wind speed or do I want other features and functions too? If you’re interested in more than just wind velocity, you may want to consider fully fledged personal weather stations that include wind cups but also measure factors like temperature, barometric pressure, rainfall, humidity and other factors. These personal weather stations can accurately predict rain and weather conditions using a variety of instruments and often come with wireless digital displays that you can keep in your home.
