Dust Sensor Module Kit - GP2Y1014AU0F with Cable
Sharp GP2Y1014AU0F optical dust sensor with LED and analog voltage output proportional to particulate concentration. Single analog output — not I2C; pair with an ADC-equipped microcontroller.
Pinout
- Blue wire
Sensor LED supply lead. Adafruit product page says connect the blue wire to 5V through the included 150 ohm resistor.
Type · PowerVoltage · 5V through 150 ohm resistor - Yellow wire
Ground lead. Adafruit product page says connect yellow wire to ground.
Type · GroundVoltage · 0V / GND - Green wire
Ground lead. Adafruit product page says connect green wire to ground.
Type · GroundVoltage · 0V / GND - White wire
LED control input. Adafruit product page says connect the white wire to a digital output to control the LED.
Type · GPIO - Black wire
Dust signal output. Adafruit product page says connect the black wire to an analog input, and describes the sensor as giving a single analog voltage output where higher voltage means dustier air.
Type · AnalogVoltage · analog output maxes out at 3.6V; dust range stated as 0 to 0.5 mg/m3 - Red wire
Sensor power lead. Adafruit product page says connect the red wire to 5V.
