Welcome to a new Voltlog, in the previous video I showed how I built this monitoring system for CO2, it’s based on an ESP32 development board and it uses two sensors the MH-Z19B and the CCS811. In that video I explained the differences between these two sensors so please watch that to better understand the current video and the conclusions presented here.

15/10/2020· The CO2 sensor is MH-Z19B, NDIR type. 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.
29/01/2021· Bitlair had one CO2 sensor based on the cheap MH-Z19b module, but this was not enough to rely on, especially because there are multiple rooms and we obviously can not measure through walls. The requirements I set out are simple, just make it possible for people to tell at a glance whether contamination risk is high or not. And as a bonus, tell whether the risk is trending up or downwards ...
