Product Description
The wind speed sensor uses the ultrasonic time difference method to measure the wind speed.
The speed at which sound travels in the air is superimposed on the speed of the airflow.
If the ultrasonic wave travels in the same direction as the wind direction, its speed will increase.
Conversely, if the ultrasonic wave travels in the opposite direction to the wind direction, its speed will be slower.
