" Overview: This passive wide infrared (PIR) wireless angular motion sensor is a PIR 433MHz RF motion detector for human detection. The PIR motion detector can work with the 433MHz RF gateway host, providing push human detected alarm message to your phone. features: * Dependable MCU technology: Our motion detector uses state-of-the-art-passive infrared (PIR) technology to detect any human movement in the detection area. Overcome false alarm. * Reliable range: Communication range is up to 100m / 328ft (the distance between the sensors at the receiver / alarm) and the detection range of the infrared sensor is around 6-8m / 20-26ft to keep you informed and completely safe. * Hidden external ON / OFF switch. Delay and low power function consume the design, low indication of LED power. * Robust and durable, suitable for homes, offices, hangars, garages, etc. Easy installation and set up, fixed to the wall. * Anti-burn blanket. dynamic temperature compensation, no blind spots.
