Sharp GP2Y1010AU0F Dust Sensor Library for Arduino/ESP32

Sharp GP2Y1010AU0F Dust Sensor Library

This is a wrapper library for Sharp GP2Y1010AU0F Optical Dust Sensor. The library is built base on this post.

Installation

1. Download ZIP file of this repository;
2. In the Arduino IDE, choose Sketch/Include Library/Add Zip Library;
3. Navigate to the ZIP file, and click Open, the library will be placed in [Arduino directory]/libraries/GP2Y1010AU0F/;
4. you should find the "GP2Y1010AU0F" in Sketch/Include Library from menu.

APIs

GP2Y1010AU0F

The constructor. Return a GP2Y1010AU0F object.

GP2Y1010AU0F::GP2Y1010AU0F(uint8_t ledPin, uint8_t measurePin)

Parameters	Type	Description
ledPin	unsigned int	Sensor infrared LED pin number
measurePin	unsigned int	Sensor analog measure pin number

begin

Setup sensor object. Return true when done.

bool GP2Y1010AU0F::begin()

read

Simply read the current dust density. Unit: ug/m³

float GP2Y1010AU0F::read()

Usage Example

/**
 * Example for using GP2Y1010AU0F Dust Sensor library
 * Created by Mickey Chan
 */

#include <GP2Y1010AU0F.h>

int measurePin = A0;   // Connect dust sensor analog measure pin to Arduino A0 pin
int ledPin     = 2;    // Connect dust sensor LED pin to Arduino pin 2

GP2Y1010AU0F dustSensor(ledPin, measurePin); // Construct dust sensor global object
float dustDensity = 0;

void setup() {
  Serial.begin(115200);
  Serial.println(F("GP2Y1010AU0F Dust Sensor Library Example"));

  dustSensor.begin();
}

void loop() {
  dustDensity = dustSensor.read();
  
  Serial.print("Dust Density = ");
  Serial.print(dustDensity);
  Serial.println(" ug/m3");

  delay(5000);
}
