GP2Y1010AU0F Optical Dust Sensor

GP2Y1010AU0F is an optical dust sensor designed to detect air quality and fine dust particles, including smoke. It operates using an optical sensing system that includes an IR light-emitting diode (IRED) and a phototransistor arranged diagonally to detect reflected light from dust particles. This sensor is known for its low power consumption, typically around 11mA, and can operate within a voltage range of 4.5V to 5.5V. It is highly sensitive, capable of detecting dust particles as small as 0.5µm with a sensitivity of 0.5V/(100 µg/m³). Common applications for this sensor include air purifiers, air conditioners, and air quality monitors. The sensor has a straightforward pin configuration, including VCC, GND, and an output pin for connecting to an analog input.
