YF-2124B Ultrasonic Wind Speed and Direction Sensor
Ultrasonic wind speed and direction sensor with no moving parts and RS485 Modbus RTU output.
Product Overview
The YF-2124B Ultrasonic Wind Speed and Direction Sensor measures wind speed and direction using ultrasonic technology. It calculates wind speed from differences in ultrasonic signal travel time and determines wind direction from signals received in different directions.
The sensor has no moving parts and supports RS485 communication using the Modbus RTU protocol. It can be connected to a computer, data logger or other compatible RS485 data acquisition equipment.
