Product Overview: One sensor does it all. The product is a new energy-saving switch adopts the good sensitivity detector, integrated circuit and SMT. It gathers automatic, convenient safe, energy-saving and practical functions. Three detectors inside compose a wide range detection field. They utilize the infrared energy from human as control-signal source to start the load at once when human enter detection field. And they can identify day and night automatically. It is easy to install and used widely, possessing the power show and detection show functions. Sensor Function: All funtions are set by remote controller accurate LED numeric display time-delay function: it can be accurate to sec, -999sec for your choice, operation simple and using convenient; impluse mode is another new function, when one enters its sense range, it will start load to turn on 0.5sec, that give effect of alert signal. In this mode, the sense time interval is adjustable, default is 50sec; SET TIME button: used to set time; Switch: convert NORMAL mode and IMPULSE mode; SENSE LED; Sensitivity (SENS) is adjustable; Light control (LUX) is adjustable.
