MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

2021-06-12· The MH-Z19 library by Jonathan Dempsey is, as the name suggests, written specifically for the MH-Z19 sensors. It works with both the B and C variants. My attempt to use it for the MH-Z14 failed. The MH-Z19 library is characterized by the fact that it uses many of the undocumented commands, such as the query of the range or the firmware version. Thanks to the many example sketches, it is easy ...

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 ...
