This project aims to calculate PPM (Parts Per Million) using 15 different gas sensors, each with individually created slopes. You don't need to worry about calibration; the process is fully automated by the library. The multi-gas sensor system is highly flexible with its plug-and-play feature and adjustable structure, enabling users to easily select the desired gas sensor.
