*GitHub : https://github.com/rdiot/rdiot-s065.git


* Specs

GP2Y1010AU0F is a dust sensor by optical sensing system An infrared emitting diode (IRED) and an phototransistor are diagonally arranged into this device It detects the reflected light of dust in air. Especially, it is effective to detect very fine particle like the cigarette smoke In addition it can distinguish smoke from house dust by pulse pattern of output voltage Compact, thin package (46.0 × 30.0 × 17.6 mm) Low consumption current (Icc: MAX. 20 mA) The presence of dust can be detected by the photometry of only one pulse Enable to distinguish smoke from house dust Lead-free and RoHS directive compliant Compliant with RoHS directive (2002/95/EC)
