The PM2.5 GP2Y1010AU0F Dust Smoke Particle Sensor uses an infrared emitting diode (IRED) and a phototransistor arranged diagonally to detect the reflected light of dust in the air. It is particularly effective in detecting fine particles such as cigarette smoke and can distinguish between smoke and house dust based on the output voltage pulse pattern.
