Exemplu cod :

/* MQ-8 Hydrogen Sensor Circuit with Arduino */

const int AOUTpin=0;  //the AOUT pin of the methane sensor goes into analog pin A0 of the arduino
const int DOUTpin=8;  //the DOUT pin of the methane sensor goes into digital pin D8 of the arduino
const int ledPin=13;      //the anode of the LED connects to digital pin D13 of the arduino

int limit;
int value;

void setup() {
Serial.begin(115200);  //sets the baud rate
pinMode(DOUTpin, INPUT);  //sets the pin as an input to the arduino
pinMode(ledPin, OUTPUT);   //sets the pin as an output of the arduino
}

void loop()
{
value= analogRead(AOUTpin);  //reads the analaog value from the methane sensor’s AOUT pin
limit= digitalRead(DOUTpin);   //reads the digital value from the methane sensor’s DOUT pin
Serial.print(„Methane value: „);
Serial.println(value);  //prints the methane value
Serial.print(„Limit: „);
Serial.print(limit);   //prints the limit reached as either LOW or HIGH (above or underneath)
delay(100);
if (limit == HIGH){
digitalWrite(ledPin, HIGH);  //if limit has been reached, LED turns on as status indicator
}
else{
digitalWrite(ledPin, LOW);  //if threshold not reached, LED remains off
}
}
