This page is about the MH-Z19 CO2 sensor and some experiments done with it:
Using the MH-Z19 CO2 sensor PWM readout, simple arduino code:

Immerhin kann man den Sensor per Hd-Pin (7s gegen GND) auf 400ppm (Außenluft) eichen.
CCS811
CCS BME combo
This one I ordered 2.... but check I2C adress. and connect "WAK" to GND
- #define CCS811_ADDR 0x5A //Alternate I2C Address
- myBME280.settings.I2CAddress = 0x76;
