Dust Smoke Particle Sensor An infrared emitting diode (IRED) and a phototransistor are diagonally arranged into this device. It detects the reflected light of dust in the air. Especially, it is effective to detect very fine particle like the cigarette smoke. In addition, it can distinguish smoke from house dust by the pulse pattern of the output voltage.

Main features:

  1. PWM output mode
  2. Compact, lightweight
  3. Easy to install
  4. A single power supply
  5. Low prices.

Main applications:

  1. Air purifiers and air cleaners
  2. Air-conditioning
  3. The air quality monitoring instrument
  4. Air conditioning and other related products

The main parameters:

  1. The optical principle, be able to detect more than 1-micron dust particles
  2. The two output modes, solve different sensitivity requirements
  3. High output signal Vout clean environment (4V)
  4. 5VDC power supply
  5. Detecting particles range : up to 8000pcs / 283ml (1um particles above )

The Sharp Optical Dust Sensor (GP2Y1010AU0F) is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems.

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.

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.

For your convenience, ITEAD ship this sensor with a 6-pin, 1.5mm pitch mating connector and cable.

int ledPower=2;

int delayTime=280;

int delayTime2=40;

float offTime=9680;

void setup(){



pinMode(dustPin, INPUT);

ledPower is any digital pin on the arduino connected to Pin 3 on the sensor








if (dustVal>36.455)



Test data and air quality control:

3000 + = very poor

1050-3000 = error

300-1050 = General

150-300 = good

75-150 = very good

0-75 = very good

Routine 2, test code: final concentration value.

int measurePin = 0; Connect an analog port 0, that is, routine 1 dustPin

int ledPower = 2; Connecting digital pins 2

Int samplingTime = 280;//LED turn on period of time was 280 μ s

Int deltaTime = 40;//the whole pulse duration of 320 μ s. Therefore, we needed to wait 40 μ s

int sleepTime = 9680;

float voMeasured = 0;

float calcVoltage = 0;

float dustDensity = 0;

void setup(){




void loop(){


Open internal LED

delayMicroseconds(samplingTime); 280us waiting time after the opening LED

voMeasured = analogRead(measurePin); Read analog values

delayMicroseconds(deltaTime); 40us wait time


Turn off LED


0 - 5V mapped to 0 - 1023 integer values

recover voltage

calcVoltage = voMeasured * (5.0 / 1024.0); Analog values into a voltage value

dustDensity = 0.17 * calcVoltage - 0.1; To output the voltage value to a dust density units

Serial.print("Raw Signal Value (0-1023): ");


Serial.print(" - Voltage: ");


Serial.print(" - Dust Density: ");

Serial.println(dustDensity); Final concentration value, output units: mg/m³



Note: the above two of the wiring is the same as the code under test, you don't have to change, and then you can just burn to write code to test.

Note:Add aA 150ohm resistor and a 220uF capacitor, wiring the following figure!

Sensor Pin Arduino Pin

1 Vled -> 5V (150ohm resistor)


3 LED -> Digital pin 2

4 S-GND -> GND

5 Vo -> Analog pin 0

6 Vcc -> 5V

LED pins must be adjusted to 1ms cycle, discussed in a data table.

LED appears to be PNP transistors to power on LED pins must accept a lower voltage.
