GP2Y1010AU0F Compact Optical Dust Sensor Smoke Particle Sensor with Cable for Arduino

GP2Y1010AU0F Compact Optical Dust Sensor Smoke Particle Sensor with Cable for Arduino

Description:
- GP2Y1010AU0F is a dust sensor by optical sensing system    
- An infrared emitting diode (IRED) and an phototransistor are diagonally arranged into this device    
- It detects the reflected light of dust in air.    
- Especially, it is effective to detect very fine particle like the cigarette smoke    
- In addition it can distinguish smoke from house dust by pulse pattern of output voltage    
- Compact, thin package (46.0 × 30.0 × 17.6 mm)    
- Low consumption current (Icc: MAX. 20 mA)    
- The presence of dust can be detected by the photometry of only one pulse    
- Enable to distinguish smoke from house dust    
- Lead-free and RoHS directive compliant    
- Compliant with RoHS directive (2002/95/EC)    

Specification:

Example 1, testing code:
int dustPin=0;
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 3 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);
}

The data and qir quality:
3000+ =worse
1050-3000 = worse
300-1050 = average
150-300 - good
75-150 = better
0-75 = best

Examplt 2 testing code: the final Concentration
int measurePin = 0; // connect the analog port 0, that is the dustPin of example 1
 
int ledPower = 2;//connect the number 2 port
 
int samplingTime = 280;//the starting time of  LED is 280μs
 
int deltaTime = 40;//the whole pulse is 320μs. So we have to wait for 40μs
 
int sleepTime = 9680;
 
float voMeasured = 0;
 
float calcVoltage = 0;
 
float dustDensity = 0;
 
void setup(){
 
Serial.begin(9600);
 
pinMode(ledPower,OUTPUT);
 
}
 
void loop(){
 
digitalWrite(ledPower,LOW); //start LED
 
delayMicroseconds(samplingTime); // turn on LED,waiting time 280μs
 
voMeasured = analogRead(measurePin); // read the analog value  
 
delayMicroseconds(deltaTime); // waiting time40μs
 
digitalWrite(ledPower,HIGH); // off LED
 
delayMicroseconds(sleepTime);
 
// 0 - 5V mapped to 0 - 1023 integer values
 
// recover voltage
 
calcVoltage = voMeasured * (5.0/1024.0); //turn the analog to voltage
 
dustDensity = 0.17 * calcVoltage - 0.1; //turn the voltage into dust density unit
 
Serial.print("Raw Signal Value (0-1023):");
 
Serial.print(voMeasured);
 
Serial.print(" - Voltage:");
 
Serial.print(calcVoltage);
 
Serial.print(" - Dust Density:");
 
Serial.println(dustDensity); // final concentration, mg/stere
 
delay(1000);
 
}
