The PIR45 includes two sensitivity detectors and an integrated circuit to save energy and offer practical functions. The PIR45 has a wide detection field for up to 20m and is designed to automatically turn lights on when motion and body heat is detected. The sensor uses the infrared energy from humans as a control-signal source; the load is activated as soon as one enters the detection field. It includes a day/night sensor to easily identify between day and night, and it is easy to install. Application: Major Tech PIR Sensor is ideal for homes, offices and hotels The main applications include corridors, pathways, bathrooms and lobbies Features : 360° Detection Field Automatically turns on lights when motion and body heat is detected 3 – 2000 LUX (Adjustable) Installation height 4 – 10m Identify day and night automatically Time-delay and ambient light adjustment Detection distance 20m (max) Power consumption 0.5W Detection moving speed 0.6 – 1.5m/s
