Fermion: MEMS Odor Smell Gas Detection Sensor

1. Example Code for Arduino-Read Sensor Raw Value

This project demonstrates how to read the raw analog value from the Fermion: MEMS Odor Sensor using an Arduino board. Users will learn how to connect the sensor to the Arduino, read the analog output signal, and view the raw sensor values via the serial port monitor.
