The PIR sensor detects movement at a distance of up to 6 metres across a wide 120° angle. Use it for automatic light switching, securing an area, or triggering your own smart home scenarios.
The built-in light sensor enables more precise automations—for example, switching on the light when movement is detected only when the room is dim or dark.
The compact sensor can be attached magnetically, with adhesive tape, or using screws. The CR2477 battery provides power for up to 3 years of operation, so frequent battery replacement is not necessary.
The SONOFF SNZB-03PR2 motion sensor reliably detects movement and helps automatically respond to activity in your home. After detection, you can, for example, switch on the lights, trigger an alarm, activate other smart devices, or receive notifications on your phone. The adjustable retrigger time allows you to tailor the automation to a specific room.
The integrated light sensor expands the possibilities of a smart home—the lighting can be switched on only after dark or at a selected brightness level. The sensor communicates via Zigbee 3.0 and works with a compatible Zigbee gateway. It supports the eWeLink, Home Assistant, Google Home, SmartThings, and Apple Home ecosystems via a Matter bridge.
Easy installation is possible using the magnetic base, adhesive tape, screws, or by placing the sensor on a flat surface. The package includes the sensor, magnetic mounting base, mounting pins and screws, user manual, and quick-start guide. When connected to Amazon Alexa devices with a built-in Zigbee hub, light intensity measurement, brightness calibration, and OTA updates are not available; the detection time can be set using the button on the sensor.
