Mh Z19 - For Arduino Boards (&ESP32). Additional Examples ...

Advice: The MH-Z19 works best in the Range of 2000ppm, outside of this accuracy begins to fall away. This is supported by documentation by also by features such as the Analog Out. I would suggest keeping to this range if you need accuracy and a maximum of 5000ppm. Relevant Datasheets. The Englisih datasheet for the MH-Z19: MH-Z19. The English datasheet for the non-JST MH-Z19B version: MH …
