Sharp GP2Y10 Optical Dust Sensor

An infrared emitting diode (IRED) and a phototransistor are diagonally positioned in this PM2.5 GP2Y1010AU0F Dust Smoke Particle Sensor. It detects dust in the air by detecting reflected light. It is especially useful for detecting very small particles, such as cigarette smoke. Furthermore, the pulse pattern of the output voltage may distinguish smoke from house dust. The module is mostly used with dust removal equipment, air purification equipment, dust robots, and fire alarms, etc. Industry equipment can detect smoke particles, pollen spores, and other particles. It can be used with lots of microcontroller platforms such as Arduino with a connection of 150Ω resistor and 220 µF capacitor.
