It can autom tically open all kinds of equipments, inculding incandescent lamp, fluorescent lamp, intercom, automatic, electric fan, dryer and automatic washing machine, etc. It is widely used in enterprises, hotels, stores, and corridor and other sensitive area for automatical lamplight, lighting and alarm system. Instructions Induction module needs a minute or so to initialize. During initializing time, it will output 0-3 times. One minute later it comes into standby. Keep the surface of the lens from close lighting source and wind, which will introduce interference. Induction module has double -probe whose window is rectangle. The two sub-probe (A and B) is located at the two ends of rectangle. When human body move from l ft to right, or from right to left, Time for IR to reach to reach the two sub-probes differs.The lager the time diffference is, the more sensitive this module is. When hum n body moves face-to probe, or up to down, or down to up, there is no time difference. So it does not work. So instal the module in the direction in which most hum n activities behaves, to guarantee the induction of human by dual sub-probes. In order to increase the induction range, this module uses round lens which can induct IR from all direction. However, induction from right or left is more sensitivity than from up or down.
