20210612· 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 ...
The MHZ19 is a small nondispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should increase ventilation. Note: the new version MHZ19B requires the VIN to be ...
Advice: The MHZ19 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 MHZ19: MHZ19. The English datasheet for the nonJST MHZ19B version: MH …
