Dust Particle Measurement with GP2Y1010

Introduction

This experiment demonstrates how to measure the concentration of dust particles in the air using the GP2Y1010 dust sensor.

Components Needed

• GP2Y1010 Dust Sensor
• Arduino
• Jumper Wires

Circuit Setup

1. Connect the GP2Y1010 sensor’s VCC and GND pins to 5V and GND on the Arduino.
2. Connect the output pin to an analog input pin (e.g., A0) on the Arduino.

The GP2Y1010 sensor detects dust particles in the air, and the Arduino processes the signal to calculate the particle concentration.

Code for Dust Particle Measurement

Upload the following code to your Arduino to measure dust particle concentration:

const int dustPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int dustConcentration = analogRead(dustPin);
  Serial.print("Dust Concentration: ");
  Serial.println(dustConcentration);
  delay(1000);
}
            

Explanation

The GP2Y1010 sensor detects light scattering caused by dust particles in the air. The Arduino reads the analog value to determine the dust concentration.

Troubleshooting

• Check the wiring and ensure the sensor is receiving power.
• If the sensor isn’t detecting dust, ensure it is placed in an area with airborne particles.
