Sonoff PIR3 RF Motion Sensor

The Sonoff PIR3 RF motion sensor is a compact, wireless passive infrared (PIR) sensor used for home security and automation, which requires a Sonoff 433MHz RF Bridge to function with the eWeLink app and other smart devices.

Key Features:

• Connectivity: Uses 433MHz RF communication to link with a compatible Sonoff RF Bridge.
• Remote Notifications & Smart Scenes: When paired with the RF Bridge, the sensor sends motion alerts to your smartphone and can trigger smart scenes, such as turning on lights when movement is detected.
• Camera Binding: Allows binding a Sonoff IP camera to the sensor, so you can monitor the detected area for double insurance.
• Two Working Modes:
  • Alert Mode: Triggers an alert every 5 seconds if motion is continuously detected within the range.
  • Normal Mode: Triggers an alert only if no motion is detected for at least 1 minute after the previous detection, which helps with energy efficiency in high-traffic areas.
• Installation: Can be installed using the included 3M adhesive or screws (a separate universal joint can be purchased for optimal 360° horizontal and 90° vertical angle adjustment).
• Compact Size: Its small and compact design (approx. 40 x 35 x 28mm) allows it to be placed discreetly in various locations.
