The Sonoff PIR3-RF utilizes a passive infrared (PIR) sensing element to detect the movement of warm bodies, such as humans or pets, within its detection zone. It transmits detection events wirelessly via 433MHz RF signals, enabling seamless integration with compatible Sonoff RF Bridges and smart home ecosystems for automated lighting, security alerts, and scene triggering.
Engineered for versatile deployment, the sensor housing is constructed from PC V0 flame-retardant material and operates reliably within an indoor temperature range of -10°C to 40°C. Its compact form factor and multiple mounting options—including a 3M adhesive pad and a screw-mount universal joint—allow for optimal placement in hallways, rooms, or entryways to maximize coverage and detection accuracy.
