GP2Y1010AU0F Optical Dust Sensor

GP2Y1010AU0F sensor also known as optical air quality sensor used to Sense Dust Particles. This compact-sized optical sensor consists of works by detecting the reflected light of dust in the air. It is an ideal solution to detect very fine particles like cigarette smoke. Moreover, it also determines the smoke from house dust by pulse pattern of output voltage, thus commonly used in air purifier systems. The sensor features very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC. The output of the sensor is an analogue voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3. GP2Y1010AU0F sensor operates at a voltage range of 4.5V to a maximum of 5.5V DC supply voltage.

GP2Y1010AU0F dust sensor consists of an infrared emitting diode and a phototransistor diagonally arranged into this device system. This works on the principle of Laser Scattering. Therefore the Infrared emitting diode in the sensor illuminates the particles in the air that enters through the air inlet. And this scattered light is transformed into a form of the signal by a phototransistor. Further, the amplifier circuit amplifies these signals and is then processed to obtain the particle concentration. The intensity of the scattered light depends on the dust particles.

The more the dust particles in the air, the greater will be the intensity of light. Thus the Output voltage at the VOUT pin of the sensor varies according to the intensity of scattered light. Moreover, this module offers a wide range of applications in dust removal equipment alarm equipment, air purification equipment, dust robots, fire alarm, etc.
