The Sonoff PIR2 is a 433MHz RF Sensor which will work together with the Sonoff RF bridge. The sensor ultra-low power and uses two AA (3V) battery's which are not included. When the sensor detects movement (12m x 12m area) sensor sends a 433.92MHz signal to the Sonoff RF bridge, triggering an scene or alarm in the eWeLink app.
