· The MHZ19 library by Jonathan Dempsey is, as the name suggests, written specifically for the MHZ19 sensors. It works with both the B and C variants. My attempt to use it for the MHZ14 failed. The MHZ19 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 ...

MHZ19 CO2 sensor | MySensors Forum

· If you mean the MG811 on that list: it''s pretty bad. Long warmup times (24 hours..) Needs 6v; Doesn''t really measure CO2, but responds to all kinds of other gasses too. Loses callibration. It''s mostly a chemical proces. The cool thing about the MHZ14 and the even better MHZ19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in ...
