Wind sensor function and role

What are the functions and roles of wind sensors?

　　The wind sensor is a physical device that detects and senses the wind direction information through the rotation of the wind direction arrow, and transmits it to the coaxial code plate, and outputs the corresponding wind direction related value.

　　The main body of the wind sensor generally adopts the mechanical structure of the wind vane. When the wind blows to the end of the wind vane, the arrow of the wind vane will point to the wind direction. In order to maintain sensitivity to the wind direction, different internal mechanisms are also used to identify the wind direction of the wind speed sensor.

　　There are three general types.

　　Electromagnetic wind sensor: designed according to the electromagnetic principle, because there are many kinds of principles, so its structure is different. At present, some sensors have started to use gyroscope chip or electronic compass as the basic components, and its measurement accuracy is further improved.

　　Photoelectric wind sensor: This wind sensor takes absolute gray code disk as the basic component, uses special customized code, based on the photoelectric signal conversion principle, and can accurately output the corresponding wind information.
