==Description==
EASY plug GP2Y1014AU PM2.5 Dust sensor is particularly effective in detecting very fine particles, such as cigarette smoke, and is commonly used in air purifier system. <br>
In the device, an infrared light emitting diode and a phototransistor are diagonally arranged to allow it to detect the light reflected by dust in the air. <br>
The sensor has very low current consumption (up to 20mA, typical of 11 mA) and can carry up to 7VDC sensors. <br>
The output is an analog voltage proportional to the measured dust concentration, with a sensitivity of 0.5V/0.1mg/m3.<br>
The sensor's four pins are led out as Registered Jack, allowing you to connect it to EASY plug Control board V2.0 for communication with only an RJ11 cable.  <br>

<br>
==Technical Details==
*Power supply voltage: 5-7V
*Working temperature: -10 to +65 degrees Celsius
*Current consumption: 20mA maximum
*Minimum particle detection: 0.8 microns
*Sensitivity: 0.5V/(0.1mg/m3)
*Voltage in clean air: 0.9V (typical)
*Working temperature: -10°C to 65°C
*Storage temperature: -20°C to 80°C
*Service life: 5 years
*Dimensions: 35.6mm × 69.7mm × 28mm
*Weight: 27g

Example 1:  <br>
Connect It Up:  <br>
<br>[[File:ks0381.jpg|600px|frameless|thumb]]<br>

Upload the Code 1:  <br>
Copy and paste below code to Arduino IDE and upload.  <br>
Note: Before compile the code, do remember to put the libraries needed inside the libraries folder of Arduino IDE directory. Or else, it will fail to verify.   <br>
You can download all the libraries from the link below:   <br>

<pre>
#include <Wire.h> 
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,20,4);  // set the LCD address to 0x27 for a 16 chars and 2 line display
int measurePin = 6; //Connect dust sensor to Arduino A6 pin
int ledPower = 2;   //Connect 3 led driver pins of dust sensor to Arduino D2
int samplingTime = 280;
int deltaTime = 40;
int sleepTime = 9680;
float voMeasured = 0;
float calcVoltage = 0;
float dustDensity = 0;
void setup(){
  lcd.init();                      // initialize the lcd 
  lcd.init();
  // Print a message to the LCD.
  lcd.backlight();
  lcd.setCursor(0,0);
  lcd.print("Raw Signal Value: ");
  lcd.setCursor(0,2);
  lcd.print("Voltage:");
  lcd.setCursor(0,3);
  lcd.print("Dust Density:");
  pinMode(ledPower,OUTPUT);
}
void loop(){
  digitalWrite(ledPower,LOW); // power on the LED
  delayMicroseconds(samplingTime);
  voMeasured = analogRead(measurePin); // read the dust value
  delayMicroseconds(deltaTime);
  digitalWrite(ledPower,HIGH); // turn the LED off
  delayMicroseconds(sleepTime);
  // 0 - 5V mapped to 0 - 1023 integer values
  // recover voltage
  calcVoltage = voMeasured * (5.0 / 1024.0);
  // linear eqaution taken from http://www.howmuchsnow.com/arduino/airquality/
  // Chris Nafis (c) 2012
  dustDensity = 0.17 * calcVoltage - 0.1;
  lcd.setCursor(1,1);
  lcd.print(voMeasured);
  lcd.setCursor(9,2);
  lcd.print(calcVoltage);
  lcd.setCursor(14,3);
  lcd.print(dustDensity);
  delay(1000);
}
</pre>

<br>
Example Result: <br>
Done uploading the code, you should be able to see the measured dust density is showed on the LCD screen.

Example 2:  <br>
Connect It Up: <br>
<br>[[File:ks0381.jpg|600px|frameless|thumb]]<br>

Upload the Code 2:
<pre>
int dustPin=6;
float dustVal=0; 
int ledPower=2;
int delayTime=280;
int delayTime2=40;
float offTime=9680;

void setup(){
Serial.begin(9600);
pinMode(ledPower,OUTPUT);
pinMode(dustPin, INPUT);
}
 
void loop(){
// ledPower is any digital pin on the arduino connected to Pin 2 on the sensor
digitalWrite(ledPower,LOW); 
delayMicroseconds(delayTime);
dustVal=analogRead(dustPin); 
delayMicroseconds(delayTime2);
digitalWrite(ledPower,HIGH); 
delayMicroseconds(offTime);
delay(1000);
if (dustVal>36.455)
Serial.println((float(dustVal/1024)-0.0356)*120000*0.035);
}
</pre>
<br>
Example Result: <br>
Done upload the code, open the Arduino IDE’s serial monitor, and set the baud rate to 9600, you should be able to see the data.

<br>
Compare the measured data to the air quality: <br> 
*3000+ = very poor 
*1050-3000 = poor 
*300-1050 = general 
*150-300 = good 
*75-150 = very good 
*0-75 = excellent
