A wind direction sensor, commonly referred to as a wind vane, operates by aligning itself with the direction of airflow and converting this orientation into an electrical signal. The front of the wind direction sensor is designed with an aerodynamic fin that naturally rotates until it faces the incoming wind, stabilizing along the true wind direction. High-precision position detection elements—such as magnetic encoders, potentiometers, or Hall-effect sensors—then measure the vane’s angular position and output corresponding directional data in degrees.
In more advanced ultrasonic wind direction sensor models, paired transducers evaluate differences in sound wave travel time across multiple axes to determine wind direction without moving parts. These sensors offer high reliability, fast response, and minimal maintenance.
