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 ...

Have you ever wondered how fast the wind is blowing when gusty winds are in the forecast? Meteorologists use an anemometer, a device that measures wind speed, to figure out how fast the wind is ...

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 ...

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 ...

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 ...

Awhile back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair. The resulting sensor is simple, sensitive, and solid-state, but suffers ...

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 ...

At the heart of a thermal anemometer are two sensors: an air velocity sensor and a temperature compensation sensor. The velocity sensor is heated to an elevated temperature (relative to the ...

Typically, air flow is measured with a hot-wire anemometer. Here's an alternative version of that concept using two thin-film platinum resistance temperature detectors. A high-performance mixed-signal ...
