Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane. For [Jianjia ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need any ...

Add Yahoo as a preferred source to see more of our stories on Google. Have you ever wondered how fast the wind is blowing when gusty winds are in the forecast? Meteorologists use an anemometer, a ...

An anemometer is a tool used to measure wind speed. It has three or four cups attached to horizontal arms and when the wind blows, the cups rotate around. The stronger the wind blows, the faster the ...

Above: The Mount Washington Observatory on an icy winter day. It was here that a wind gust of 231 mph was measured on April 12, 1934. It remained the highest-ever anemometer-measured wind gust on ...

This self-heated constant-temperature-delta transistor anemometer is cheap, rugged, and sensitive. It relies on the relationship between airspeed (AF) and thermal impedance (ZT = o C/W) of a heated ...

All thermal anemometers work by inferring air speed from measurements of thermal impedance (Z) between a heated sensor and the surrounding air: An example of the constant power type can be found in ...

If you are interested in creating a DIY Arduino wind speed meter or anemometer to monitor the wind strength in your location, you might be interested in this quick tutorial I have put together to ...

Thermistors use a thermally active resistor made of metal oxides encased in epoxy or glass. The resistance output varies based on temperature. A more accurate thermister will vary linearly throughout ...
