Problem with CO2 sensor MHZ19B cannot read values ...

20200413· Thanks a lot for your comments. After many hours of another triesandfails I decided to completely rebuild the wiring and also the code. Too many lines of (un)commented code, too many wires. And voilà, it works. Unfortunately I cannot say, what was wrong. Maybe some bad joint. The wiring is the same as simple as on the beginning (without level converter, so 5V level of UNO). The code is only ...

Mh Z19

The value stored on the MHZ19 and is set to 400ppm. This is used as the zeroing point. Zero Calibration: This can be made in two ways: By pulling the zero HD low (0V) for 7 Secs, or be sending command 135 (0x87). As above, the Zero refers to the background CO2 value of 400ppm, not 0ppm. Currently testing is the ability to send an adjustment with command at byte 7, however it is unclear the ...
