npm install node-red-contrib-mh-z19-co2sensor With this node you can read the CO2 values of your MH-Z19 CO2 sensor. You can also use this node to configure your sensor.
12/06/2021· 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 ...
