The QS-09 PIR Motion Sensor is a high-performance wall-mount motion detector designed for smart, energy-efficient lighting automation. With a wide 180° sensing angle and an impressive detection distance of up to 12 meters, it ensures reliable motion detection across large corridors, rooms, entrances, and garages. Equipped with adjustable time delay and LUX sensitivity control, the sensor automatically adapts to ambient light levels and user-defined operation needs, switching lights on only when movement is detected and turning them off after the set duration.
