Infrared CO2 module MH-Z19B Module …

In this project we are using MH-Z19B Infrared Co2 Module. We 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. You can see the output on the serial monitor.
