The Sharp GP2Y1010AU0F optical dust sensor is a small (46.0 × 30.0 × 17.6 mm) lightweight (~15g) air quality sensor containing an infra-red LED and a phototransistor capable of detecting air-borne dust and smoke. The sensor is available from SparkFun and their distributors (Product ID: COM-09689) and has a sensitivity of 0.5V/0.1mg/m^3.
Sharp have produced a detailed datasheet for the sensor, together with a rather useful application note.
You will need:
- Arduino Uno or equivalent (e.g. the SparkFun RedBoard – product ID: DEV-12757)
- Sharp GP2Y1010AU0F optical dust sensor (SparkFun ID: COM-09689)
- 6-Way JST ZHR-6 connector housing (SparkFun ID: PRT-09690)
- 6x JST SZH-002T-P0.5 crimp pins (SparkFun ID: PRT-09728)
- 150R Resistor
- 220µF Electrolytic Capacitor
- (Hobby Components offer the sensor, pre-crimped connector, resistor and capacitor as a complete kit)
- Small Breadboard or Veroboard
- Hook-up wires
Start by reading the hook-up instructions
Then download the Dust_Sensor sketch
Don't forget to install the Timer1 library
Make sure you are using a 5V Arduino board. If you try to use a 3V3 board like the Zero, you may damage it.
