Those wanted to have clean room, those sensitive to dust and want to detect how much dust in the room, this sensor is for you. Sharp's GP2Y1010AU0F is an optical air quality sensor, 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.

The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC. The output of the sensor is an analog voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3.

To interface with the sensor you need to connect to its 6-pin, 1.5mm pitch connector; we are searching the mating connector for this. Meanwhile, you can take a look at sample interface with arduino (credit to Paul)


  • Compact, thin package (46.0 x 30.0 17.6 mm)
  • Low current consumption (Max: 20mA)
  • Typical Operating voltage: 4.5 to 5.5V (max: 7V)

Dimensions: 1.81 x 1.18 x 0.69" (46.0 × 30.0 × 17.6 mm)

Hi, you may drop an email to support@cytron.io for further inquiries. Thanks :)
Free connector cable or buy? ( S Kaewta, 25/01/2020 )
Hi, the connector is provided.
Can I use this sensor with BBC MICRO:BIT????? ( yeseong, 30/05/2018 )
Hi, yes it is compatible. For more detail, please refer to it's datasheet. Thanks.
