Optical dust sensor high sensitive dust sensor GP2Y1010AUOF

1,Description: SDC-4S1111ANK is a dust sensor that detects the dust particle concentration in air by using optical sensing method. An infrared light emitting diode (IR LED) and a photo-sensor are optically arranged in this device. The photo-sensor detects the reflected IR LED light by dust particles in air. This dust sensor can detect the small particle like cigarette smoke and it can distinguish small particles like smoke from large house dust by pulse pattern of signal
