Wind is the movement of air that is caused by the uneven heating of the earth by the sun. You can see it or grasp it but you can’t feel it.Sometimes the wind is violent ripping trees from the ground, sometimes it is gentle as it blows gentle breezes across your face on a hot summer day. Wind is the largest source of renewable energy in the United States.We use its energy to sail boats, fly kites, and dry our clothes outside.Also, we can capture its power and use it as a clean and renewable energy source for many things.5 Simple Wind Energy ExperimentsBooks about Wind EnergyMore Hands-on Activities to Learn About the WindHow to Make a Anemometer5 Simple Wind Energy ExperimentsThe Weather Science: Build a Wind Turbine experiment looks like loads of fun and will really help simplify understanding how wind can be captured and used.Preschoolers will love this Wind Tunnel Stem Project and I like that it utilizes everyday objects so there is nothing special to buy.Wind Energy STEM Activity: Building your own model WindmillDIY Wind Car: Science Lesson & Fine Motor FunThis Mass Producing LED Powering Wind Turbines in a Kid’s Workshop is a little more involved than the others and requires more supplies.

Particle size, particle pair loss etc. Such analyses have been performed extensively for PIVlab [16]. Analyses of PIV accuracy are more complicated with experimental data, as the true velocity is often unknown. Here, we present a comparison with propeller anemometer measurements (Schiltknecht MC20, MiniWater20 Micro) in a water tunnel (located at the Bremen University of Applied Sciences, water temperature 23°C, seeded with 57 µm polyamide particles). The PIV system consists of a Phantom VEO 410L camera (1280·800 pixels) and a New Wave Pegasus-PIV 200 dual cavity laser running at 400 Hz. The images were analysed in PIVlab (2 passes, interrogation areas 64·64 and 32·32 pixels with 50% overlap, ‘extreme’ correlation robustness).As can be seen in Figure 9, the anemometer has a large influence on the flow. A sphere in a moving fluid decelerates the flow in front of it (at 0°), and accelerates the flow at the sides (at 90° and 270°). We therefore chose an area at 45°, where we expect the influence from the anemometer to be minimal (lateral distance: about 40 mm). The water tunnel was running at several speeds between 0.15 and 0.6 m/s. For each speed, the anemometer reading was averaged over time. Eighteen image pairs were analysed with PIVlab for each speed. Every image pair yielded 4·7 vectors inside the red rectangle, resulting in 504 velocity measurements for each speed. The mean value of these measurements was compared to the mean anemometer reading. There is an exceptionally good agreement between the methods (see Figure 10). The linear regression has a slope of 1.0082 and an offset of 0.0002 m/s. The correlation coefficient is 0.9998, indicating a strong linear relationship between the two methods. The bias error is 0.984% and the RMS error is 2.22%. Our analysis cannot assess which of the two methods more accurately measures the true velocity. Previous tests with PIVlab [16] imply displacement estimates with an uncertainty below 0.01 pixels with synthetic images, which is also achieved by other PIV software [20]. The analysis of experimental particle images via PIV inherently has a higher uncertainty of about 0.1 pixels due to particle intensity variations between consecutive images [21].Figure 9 Propeller anemometer in a water tunnel. The flow around the anemometer was mapped using PIV. The mean flow velocity inside the red rectangle was used for the comparison.Figure 10 Comparison of flow speed measurements with PIVlab and a propeller anemometer. The relation

In real-time.Information about humidity, pressure, and temperature is available on the app’s main screen. Extra parameters: dew point, lateral and tail airflow, atmospheric density.Customize which measurements will show speed and temperature results. Set the orientation to magnetic or true north. Sunrise and sunset will be shown as an animation.Now you will never get lost because the compass with the north direction is always in your smartphone.Anemometer – Wind speed by Elton NallbatiIf you’re using an iOS device and would like to try a tool to measure wind speed, Anemometer is a great choice for you. It has an excellent yet simple design that simulates a real device. Wherever you are, you can get accurate wind data in real-time via the Internet.In order for Anemometer to get all the data, you will need to enable location. The indicators are taken from the nearest weather station, so you can consider them reliable.If you are interested in the wind not where you are now, but in another place – just find it on the map in the Anemometer application and the data will immediately appear on the screen.You will also need to choose in advance, in what format you will be shown the information – a total of 5 blocks of figures in the application. Save your favorite places in the Anemometer and you will have access to them every second.You may also like: 11 Best Decibel Meter Apps for Android & iOSWindfinder: Wind & Weather MapThis is an app for accurate weather

Introduction: How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu. - Part 1 - HardwareIntroductionSince I started with the studies of Arduino and the Maker Culture I have liked to build useful devices using junk and scrap pieces such as bottle caps, pieces of PVC, drink cans, etc. I love to give a second life to any piece or any material. A large part of the materials used here are scrap removed from some equipment and recycledWhen I started a project of a weather station for my own I realized that the measurement of the intensity and direction of the wind would not be very easy or cheap. After several months I present to you this project that uses mostly recycled materials and very cheap electronic parts easily found in any electronic store.This post has 2 parts.Part 1 - Construction of the devices Anemometer and Wind Vane Direction.Part 2 - The sketch using Arduino IDE for Esp8266 Nodemcu and transmission to ThingSpeak .See the video to know the final solution.How to build your own Anemometer using Hall Effect Sensor and Reed SwitchesProject descriptionThe anemometer is a device capable of measuring the wind speed and its direction. Using a Hall Effect sensor we will be able to count how many rotations the cups give in a period of time. The intensity of the wind is proportional to the speed of rotation of the axis. With some simple physics equations, you can determine the linear velocity of the wind, at that moment. We will explain all of them in part 2.And the direction of the wind we will measure through a windshield with a neodymium magnet and reed switches. The vane points in the direction of the wind and the magnet attached to it

Building a wind meter, or anemometer, is a fun and educational activity for kids. It’s a great way to learn about wind speed. Let’s measure the wind! Materials You’ll Need:4 small paper cups push pin new pencil with eraser on the end stiff, corrugated cardboard (enough to cut two, same-size strips, each 1.5” wide x 10” long) scissors marker ruler (for measuring) stapler modeling clay parent supervision Instructions:Color the entire outside of one paper cup with the marker.With parental supervision, cut out two same-size strips from the cardboard (1.5” wide x 10” long) Staple the two pieces of cardboard together in the center so they form an X. Staple each paper cup (laying on their sides) to the ends of the cardboard X, making sure the cups all face the same direction. Create the base: Flip the cardboard X over, so the cups are on the bottom. With parental supervision, push the pushpin through the center of the carboard X and into the eraser of the pencil. Make sure the cups can spin freely. Test it out! Take your anemometer outside on a windy day and watch it spin. You can count the number of times the colored cup passes a fixed point in a minute to estimate wind speed. The faster it spins, the stronger the wind! You can hold your anemometer, or you can create a base to hold it, by using an old plastic container & some clay in it to hold the pencil for you.Remember:Be very careful when cutting the cardboard and when using the pushpin. Ask an adult for help!Now you’re a wind scientist!
