We offer pir motion detector. A pir-based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems. They are commonly called simply "pir", or sometimes "pid", for "passive infrared detector". This wall mountpir sensor works on the principle of passive infrared detection from the infrared heat emitted by human beings. The fresnel lens of this light control motion sensor has an angle of aperture of 180'360' as it is wall mounted and therefore can only detect human motion in front of the lens and not behind it. The detection lens of the light control motion sensor is mounted on a pivot for adjusting the tilt angle to suit the application area applications: main entrancetoilet pantrystairways lifts lobbycovered parking arealockers room trial roomsoffice atm mallsand many more!!! specifications:detection range 360180power source 220-240vacpower frequency 5060hzrated load max.1200w (220-240vac)detection distance max.6m(24)time delay 10sec 3sec to 7min2min(adjustable)installation height 2.2m - 4mprotection class ip 44
