Specifications:

Detected concentration: 10 - 1000ppmCO; 10 1000ppm other combustion gases

Supply voltage: 5VDC, a50mA

Output: Digital pin or Analog pin

Analog output: 0 - 5V; the voltage increases or decreases depending on the detected concentration

TTL Digital Output

Analogue reading code example:

void setup() {

// initialize serial communication at 9600 bits per second:

Serial.begin(9600);

}

// the loop routine runs over and over again forever:

void loop() {

// read the input on analog pin 0:

int sensorValue = analogRead(A0);

// print out the value you read:
