Dust Sensor Module overview
Dust Smoke Particle Sensor An infrared emitting diode (IRED) and a phototransistor are diagonally arranged into this device. It detects the reflected light of dust in the air. Especially, it is effective to detect very fine particles like cigarette smoke. In addition, it can distinguish smoke from house dust by the pulse pattern of the output voltage.
