Sonoff PIR3-RF – 433MHz Motion Sensor for Smart Home Automation

Sonoff PIR3-RF – 433MHz Motion Sensor for Smart Home Automation

The SONOFF PIR3-RF is a compact, battery-powered PIR motion sensor that communicates on 433MHz RF. It detects movement up to 8 m away with a 100° detection angle. Paired with a SONOFF 433MHz RF Bridge, it sends alerts to the eWeLink app and triggers smart scenes with other SONOFF devices.

Motion detection up to 8 m: The passive infrared (PIR) sensor detects movement within up to 8 m in indoor spaces, with a 100° detection angle.

Alerts and scenes through the RF Bridge: The sensor talks to a SONOFF 433MHz RF Bridge, which brings it into the eWeLink app. From there you get motion notifications and can link it to lights, alarms and other SONOFF devices in smart scenes.

No wiring: It runs on a 3V CR2450 button cell, so you can place it in hallways, entrances or rooms without running cables.

Flexible mounting: The compact sensor mounts on the wall. For angle adjustment, SONOFF offers the PIR-BASE bracket separately.
