The value stored on the MH-Z19 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 ...
