Wind Speed Sensor FS-100A

FS-100A is a high strength carbon fiber based good quality wind speed sensor also know as Anemometer. FS-100A uses the traditional three cup. The wind sensor has high quality light metal body which responds to the wind speed the sensor has good wind measuring range, high resolution and accuracy.

The sensing element of the FS-100A  wind speed sensor is a three-cup wind assembly consisting of three carbon fiber cups and cup holders. A multi-tooth rotor is used along with a slit opto-coupler. When the wind cup rotates the multi-tooth rotor also starts rotating and accordingly the opto-coupler outputs pulse signal. The pulses generated is proportional to the wind speed.

Formula for wind speed calculation:

W = 0.1 + 0.0875 × f ( f≠ 0)

where W: Wind Speed in Meters/Second (m/s)

f: Pulse signal frequency

This wind speed sensor along with wind direction sensor (FX-100) is perfect for making your own weather station.
