An anemometer is a device used for measuring wind speed with additional features of wind direction, temperature and relative humidity.
It is a common instrument in weather stations, metrological departments and checking air conditioning and heating systems.

The digital anemometer measures wind speed by measuring the speed of the fan(vane), whose axis is parallel to wind direction, using a revolution counter and converting it into readable format.
