arduino - How to use an MH-Z14a CO2 sensor? - Stack Overflow

2021-03-10· How to use an MH-Z14a CO2 sensor? Ask Question Asked 3 months ago. Active 3 months ago. Viewed 107 times 0. I have to use an MH-Z14a sensor, I've tried a lot of solutions but none of them work. I ended up with wiring the PWM to the digital 2 of my Arduino Mega2560, the V+ on 5V or (non of them give something working) and V- to GND, and I tried this code: // set interrupt pin …

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

2021-06-12· I checked the accuracy of the MH-Zxx CO2 sensors with the Technoline WL 1030, a commercially available CO2 measuring device. This model was the 2021 winner of the German test institute “Stiftung Warentest” in the category of CO2 measuring instruments. Nevertheless, of course, the question arises as to how exactly it measures itself, especially since, if you look at the functionality and ...
