Below is an example code to interface the ME2-CO Module with an Arduino UNO. This code reads the analog output from the sensor and prints the CO concentration to the Serial Monitor.
// Define the analog pin connected to the AOUT pin of the ME2-CO Module
const int analogPin = A0;
// Variable to store the analog value read from the sensor
int sensorValue = 0;
void setup() {
// Initialize the Serial Monitor at a baud rate of 9600
Serial.begin(9600);
}
void loop() {
// Read the analog value from the sensor
sensorValue = analogRead(analogPin);
// Convert the analog value to a voltage (assuming 5V reference)
float voltage = sensorValue * (5.0 / 1023.0);
// Print the voltage to the Serial Monitor
Serial.print("Sensor Voltage: ");
Serial.print(voltage);
Serial.println(" V");
// Add a delay before the next reading
delay(1000);
}
