The PIR33 adopts a sensitivity detector and integrated circuit. It gathers automatism, conveniently and safely saving energy with practical functions. Is designed to automatically turn lights on when motion and body heat is detected. It utilises the infrared energy from humans as a control-signal source; it can start the load at once when one enters the detection field. It can identify between day and night, easy to install and has a wide variety of uses. Application: Major Tech PIR Sensor is ideal for homes, offices and hotels Features : 360° Detection Field Silver Housing Automatically turns on lights when motion and body heat is detected 3 – 2000 LUX (Adjustable) Installation height 2.2 -4m Identify day and night automatically Time-delay and ambient light adjustment Detection distance 6m max Power consumption 0.5W Detection moving speed 0.6 – 1.5m/s
