使用测试代码:
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);



据和空气质量对照：
3000 + = 很差
1050-3000 = 差
300-1050 = 一般
150-300 = 好
75-150 = 很好
0-75 = 非常好
