Just wanted to add that Tasmota[0] (one of the open source firmwares for ESP8266 controllers) seems to already support MH-Z19 sensors. This cuts down on the work if all you want is to measure your CO2 level: you can get a $3 Wemos and a sensor, (solder pins, figure out the sensor connector), flash Tasmota, and you'll have it already reporting on MQTT over wifi. I would argue it's even easier than installing and maintaining Linux on a RPi. [0] https://github.com/arendst/Sonoff-Tasmota |
