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 …
