Example Code for Arduino-Read Sensor Raw Value

Hardware Preparation

• DFRduino UNO R3 (or similar) x 1
• MEMS CO Sensor (SEN0564) x 1
• Jumper wires

Software Preparation

• Arduino IDE

Wiring Diagram

Other Preparation Work

The module needs to be warmed up for more than 5 minutes when powered on for the first time. It is recommended to warm up for more than 24 hours if it has not been used for a long time.

Sample Code

int sensorPin = A0;
int sensorValue = 0;

void setup()
{
  Serial.begin(9600); //Set serial baud rate to 9600 bps
}

void loop()
{
  sensorValue = analogRead(sensorPin);
  Serial.println(sensorValue);
  delay(100);
}

Result

Open the serial port monitor and get the original value of the sensor.
