CO2 meter using M5StickC -

· Preface. Cause I've been working at home and being cooped up in my room, I decided to make a CO2 meter as a guide to ventilate my room. A MOX gas type that called CCS811 showed inappropriate results for measuring actual CO2 concentration, such as higher readings due to human farting, so I use a high-precision NDIR-type MH-Z19B in this case.
