Unfortunately the datasheet does not tell anything about the particle size detected, it just tell us that this sensor is for fine particle like cigarette smoke, that is to say about 0.5micron. Especially, it is effective to detect very fine particle like the cigarette smoke.
It detects the reflected light of dust in air. An infrared emitting diode (IRED) and an phototransistor are diagonally arranged into this device. GP2Y1010AU0F is a dust sensor by optical sensing system.
This project is a dust detector that use the GP2Y1010AU0F sensor.Īttached you can also find the GP2Y1010AU0F sensor library for AVR Atmega.
