Sonoff PIR2 433MHz Human Motion Sensor for RF Bridge - Wireless Passive Infrared

The Sonoff PIR2 operates on 3V DC supplied by two AAA alkaline batteries (not included). Its ultra-low-power design, with a standby current of ≤8μA and an alarm current of ≤15mA, combined with intelligent sleep modes, enables a typical battery life of up to two years under normal usage conditions.

This sensor is designed to work wirelessly with the Sonoff RF Bridge (sold separately). After installing batteries, you pair the sensor with the bridge via the eWeLink app. The bridge then relays motion detection events to the cloud, allowing you to create automation rules and smart scenes that trigger other Sonoff or compatible smart devices.

The sensor has a maximum detection distance of 12 meters (approximately 39 feet) and a wide 110-degree horizontal detection angle. This coverage is suitable for monitoring medium to large rooms, hallways, or entryways. The sensing pattern is a fan-shaped area in front of the wall-mounted unit.

Yes, the sensor features adjustable pulse counting logic, which allows you to fine-tune its sensitivity. This setting helps minimize false alarms caused by pets or minor environmental changes by requiring a specific sequence of detection events before triggering an alert. Configuration is typically done via the paired RF Bridge and companion app.

No, the Sonoff PIR2 is designed for indoor use only. Its operating temperature range is -10°C to 50°C, and it lacks a specified IP (Ingress Protection) rating for water or dust resistance. It is intended for installation in dry, indoor environments such as homes, offices, garages, and sheds.
