3. Connect the Makerduino to Computer by the USB cable.

 

4. Download the Makerduino demo code EB - CO Sensor.zip. Unzip the code directly into the libraries folder.

 

5. Open Makerduino IDE, choose the right Board and Serial Port. Open the sketch EB_CO_Sensor.ino and upload it to the Makerduino.

The following is the demo code for EB - CO Sensor. (Note: It could be a little different from the code file downloaded. Please follow the downloaded file.)

/*

  EB - CO Sensor Demo Code

 

  The CO Sensor detect the related Gas density,

  Makerduino get the result by anologRead.

  The output value changes larger as long as the density of the gas.

  Connect the Sensor to A0 in this demo;

 

*/

 

void setup() {

  Serial.begin(9600);

}

 

void loop() {

  int sensorValue = analogRead(A0);

  Serial.println(sensorValue);

  delay(100);

}

 

6. Check the Results. After the sketch is successfully uploaded, let's open the Serial Monitor. The Monitor will display following information that when the sensor detects CO, the output value will rise. You can revised data through adjusting the potentiometer according to the actual condition.
