Optical-Dust-Sensor-Library

Optical Dust Sensor (Sharp GP2Y10) library for Arduino framework. Tested on PlatformIO, ArduinoIDE.

Examples: https://github.com/lnquy065/Optical-Dust-Sensor-Library/blob/master/example/

Schematic

Components

• Arduino Nano
• Sharp GP2Y10 Dust Sensor
• 150Ω Resistor
• 220uF Capacitor

SharpGP2Y10 Library

Using

• Include SharpGP2Y10 library

#include "SharpGP2Y10.h"

• Create SharpGP2Y10 Object with parameters

int voPin = A0;
int ledPin = 2;
SharpGP2Y10 dustSensor(voPin, ledPin);

• Get and print dust density

float dustVal = dustSensor.getDustDensity();
Serial.println(dustVal);

Constructors

• SharpGP2Y10(int voPin, int ledPin)

  • voPin: Vo (5)
  • ledPin: LED (3)
  • Notice: default vcc is 5.0v

• SharpGP2Y10(int voPin, int ledPin, float vcc)

  • voPin: Vo (5)
  • ledPin: LED (3)
  • vcc: Voltage reference (5.0, 3.3, ...)

Methods

Get fields value only

• float getDustDensityField()
• float getVotageField()
• int getADCField()

Read new value from sensor before return

• float getDustDensity()
• float getVotage()
• int getADC()
