Method of Measuring Wind Direction
Wind direction is recorded with the weathervane. By a precision potentiometer the data are converted into an electrical parameter which can be evaluated. A spring connects this low-friction potentiometer to the weathervane. Advantage of this kind of transmission is that no stays and vibrations are transmitted to the potentiometer. This results in less friction and better response, even at the lightest wind.
Wind Direction Sensor
The sensor measures wind direction and prevalent direction of horizontal airstreams.

Method of Measuring Wind Speed
Wind makes the anomometer rotate. Within the housing, a permanent magnet, which is mounted asymmetrically to a shaft, passes a magnetic sensor. This magnetic sensor transmits a pulse after every rotation. The resulting frequency is the measure for wind speed. Wind speed is evaluated by the microcontroller and transmitted by the interface.
