Built-in temperature compensation; and it has UART output and PWM output.
Oct 18, 2020· As the code I’ve found mentions the MH-Z19 and not the “B” revision, I’ve downloaded the datasheet from the manufacturer website and to my noob eyes everything checks out, but still nothing. I was wondering if somebody could guide me into the right direction as at the moment I feel completely lost… MH-Z19B Datasheet
Apr 13, 2020· I tried to read the temperature and status, but it looks the MH-Z19B is not the same as MH-Z19 and returns always status zero and temperature looks maybe 10 degrees higher (so no value minus 40, but maybe value minus 50).
