arduino - MH-Z19 CO2 sensor giving diferent values using ...

09/10/2016· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

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

12/06/2021· For the MH-Zxx CO2 sensors, a number of libraries are available. However, the selection for MH-Z14 models is smaller. I tried two libraries. 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 ...
