Dust Sensor Smoke Particle Sensor With Cable GP2Y1010AU0F Compatible

Features:

• Compact size: 46mm × 30mm × 17.6mm, easy to install.
• High sensitivity: 0.5V per 0.1mg/m³ particle concentration.
• Adjustable sensitivity via potentiometer.
• Low power consumption: operates at DC 5V ± 0.1V with 20mA peak current.
• Wide operating temperature range: -10°C to 65°C.
• Reliable and stable long-term performance.
• Simple cable connection for microcontrollers and data acquisition.

Principle of Work:

• An infrared LED emits light into the air chamber.
• Particles scatter the IR light when passing through.
• A phototransistor detects scattered light intensity.
• The electrical signal generated is proportional to particle concentration.
• Adjustable sensitivity via potentiometer to calibrate the sensor.
• Reference voltage (clean air) helps differentiate particle levels.

Pinout:

Applications:

• Air purifiers for real-time particle detection and filtration control.
• HVAC systems for indoor air quality monitoring.
• Environmental monitoring in urban and industrial areas.
• Smoke detection and fire alarm systems.
• Industrial air quality monitoring and cleanroom environments.
• Personal air quality monitors for health and safety.

Circuit Connection:

1. Connect sensor Vcc pin to Arduino 5V.
2. Connect sensor GND pin to Arduino GND.
3. Connect Vo (analog output) to Arduino A0.
4. Connect LED driver pin 1 (V-LED) to Arduino digital pin D2.
5. Connect remaining pins as shown in the circuit diagram.

Code Example (Arduino):

// Define pins
const int dustSensorPin = A0;
const int led1 = 2;
const int led2 = 3;
const int led3 = 4;

void setup() {
  pinMode(dustSensorPin, INPUT);
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);

  Serial.begin(9600);
}

void loop() {
  int dustValue = analogRead(dustSensorPin);
  float dustConcentration = 0.17 * dustValue - 0.1; // Convert to mg/m³

  Serial.print("Dust Concentration: ");
  Serial.print(dustConcentration);
  Serial.println(" mg/m³");

  // LED indication based on dust levels
  if (dustConcentration < 12.0) {
    digitalWrite(led1, LOW);
    digitalWrite(led2, LOW);
    digitalWrite(led3, LOW);
  } else if (dustConcentration < 35.0) {
    digitalWrite(led1, HIGH);
    digitalWrite(led2, LOW);
    digitalWrite(led3, LOW);
  } else if (dustConcentration < 55.0) {
    digitalWrite(led1, HIGH);
    digitalWrite(led2, HIGH);
    digitalWrite(led3, LOW);
  } else {
    digitalWrite(led1, HIGH);
    digitalWrite(led2, HIGH);
    digitalWrite(led3, HIGH);
  }

  delay(1000);
}
