Description:

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)
