arduino MHZ19 CO2 sensor giving diferent values using ...

09/10/2016· I have a MHZ19 CO2 sensor, according the datasheet 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 05000ppm, and via PWM I should have readings between 02000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I''m realized …
