This Arduino code is designed to read data from five gas sensors connected to an Arduino board. The sensors include MQ8, MQ4, MQ9, MQ7, and MQ135. The code reads analog data from these sensors and ...

This project is based on reading analog values from the MQ2 gas sensor using an Arduino. The analog readings are mapped to corresponding gas concentration levels using logarithmic plotting, following ...

The I2C bus or TWI (Two Wire Interface) allows a single master IC to share communication lines with multiple slave ICs. ... Schematic of the Arduino and TC74 sensors circuitry. Advertisement.
