Carbon Dioxide Sensor MH-Z19b - Part 1 - Hardware design | …

10/06/2019· 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 - …

[Solved] MH-Z19B provides only static max values for CO2 …

06/05/2021· I think the first issue is how you are powering the MH-Z19B module. My data sheet indicates a volt Vin spec. and it may be quite power hungry. I would power the device with a separate 5v supply. Here is a link to a thread with some pretty solid code with good debuging in reply #5 which you should be able to adapt to your node mcu software serial pins. There is also a discussion of …
