Example Code for Arduino to Read Raw Value of Fermion: MEMS H2 Sensor

This project demonstrates how to read the raw analog output value from the Fermion: MEMS H2 Sensor using an Arduino board. Users will learn how to wire the sensor to the Arduino and use basic analog read functions to retrieve real-time sensor data.

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.
