Ready to use imeplementation for CO2 sensors of the MHZ series (Intelligent Infrared CO2 Module)
Carbon Dioxide modules such as MH-Z14A, MH-Z19B (and maybe some more) are supported on Ardunino / ESP8266. Both output signal modes UART via Serial Port and PWM are suppported. See example and/or manual for wireing the mhz14a or mhz19b.

This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
