Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design ...

2019-06-10· Some time ago I have purchased online carbon dioxide (CO2) sensor module MH-Z19b. It’s a cheap and very simple sensor with the UART interface allowing concentration measurement in the range up to 5000ppm. The normal level of CO2 concentration is considered about 400-1000ppm. Higher levels lead to various negative effects like a feeling of “bad air” and so on. The concentration of 2000 ...
