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 particle like the cigarette smoke. In addition, it can distinguish smoke from house dust by the pulse pattern of the output voltage.
Main features:1, PWM output mode ; 2 , compact, light weight ; 3 , easy to install ; 4 , a single power supply ; 5, low prices.
