This product is a sensor that senses wind speed or airflow, equivalent to a pneumatic switch, with a minimum perceived wind speed of 200ml/min,The perceived wind speed can be adjusted as needed; It can be applied to various devices in the central air conditioning duct, such as ultraviolet lamps, air purifiers, etc., to achieve linkage with the central air conditioning fan, and can also be applied to fault detection sensors for various types of fans.
Features and Benefits：
[1] Adopting high-performance sensors； [2] Sensitive, reliable, and intelligent sensing, saving costs； [3] The minimum perceived wind speed is 0.3m/s, and the perceived air volume is adjustable; [4] Effectively achieve fan linkage and fan integration； [5] The relay operates when there is wind, the relay disconnects when there is no wind； [6] Strong load control capability；
Specification:

Control logic:
The LED green light is running indicator light, and the LED red light is power indicator light. After about 45s of power on, the default state of the sensor is wind, then the relay is closed, the LED green light is on and the LED red light is on. After about 45s, execute the following logic: when the airflow sensor senses wind, the LED green light and LED red light will turn on, the relay will close, and the corresponding voltage will be output; When there is no wind, the LED green light is off and LED red light is on, the relay is disconnected, there is no voltage output, and the controller is in standby mode. (LED red light: power indicator light; LED green light: wind indicator light; the wind green light is on when there is wind, and the green light is off when there is no wind)
