An overview of the Sharp optical dust sensor (GP2Y1010AU0F) in the detection of very fine particles, such as cigarette smoke, is particularly effective, And is commonly used in air purification systems


The device, an infrared light emitting diode and a phototransistor, diagonally arranged to allow the detected light reflected from the dust in the air


The sensor has an extremely low current consumption (maximum 20mA,11 Ma typical), can carry up to 7VDC sensors. Is an analog voltage output proportional to the measured concentration, sensitivity and 0.5V/0.1mg/m3



Power supply voltage: 5-7V

Operating temperature:-10-65 degrees Celsius

Current consumption: 20mA maximum

Smallest particles detected value: 0.8 micron

Sensitivity: 0.5V/(0.1mg/m3)

Clean-air voltage: 0.9V typical

Operating temperature:-10~65°

Storage temperature:-20~80°
