How to Interface With Optical Dust Sensor : 9 Steps (with Pictures ...

Sharp's GP2Y1010AU0F is an optical air quality sensor, or may also known as optical dust sensor, is designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems. To …

Application note of Sharp dust sensor GP2Y1010AU0F

If dust attached within this sensor increases, Voc becomes bigger. On the other hand, if dust attached within this sensor decreases, Voc becomes smaller. ・To store Voc in the memory of application is necessary to calculate ΔV from monitor value Vo. If monitor value Vo lower than the memorized Voc appears, this monitor value Vo should be stored in the memory of application as a new Voc. ・If …

Arduino / PM10 Pollution Sensor based on Sharp Optical Dust …

Despite dust sensor specification promises that it would work in different temperature conditions from −10 to +65 °C, but according to experiment results with open/closed sensor hole, it calculates different values depending on ambient temperature. Also I’ve observed significant pollution data right after dust sensor is moved from cold to warm area. It could be caused by water fog condensation on cold …
