Description
The SONOFF PIR3-RF is a battery-powered wireless PIR motion sensor that communicates on 433MHz RF. When it detects movement, it can trigger compatible SONOFF RF devices for smart lighting, alarms, security notifications and automation scenes.
With no wiring needed, you can place it in hallways, entrances, rooms, offices and garages. It detects motion up to 8 m away with a 100° detection angle, and works with SONOFF RF gateways to bring alerts and scenes into the eWeLink app. It is available on its own or together with the SONOFF PIR-BASE adjustable mounting bracket.
Note: to receive alerts and create scenes in the eWeLink app, you need a SONOFF 433MHz RF Bridge (see "Works With" below).
