I wrote a little sketch for an ESP8266 to read out an MH-Z19 CO2 sensor: https://github.com/bertrik/mhz19
This sensor uses the optical measurement principle, which is supposed to be superior to electro-chemical sensors.
This kind of sensor used to be quite expensive, but now it can be found on sites like aliexpress for about E22,-
The code probably be easily ported to other processors, the sensor needs a voltage of at 3.6V-5.5V and interfaces using a UART at 3.3V.

And maybe also combined with the peripheral oxygen saturation SpO2. Hosipitals use these sensors to see if there is enough oxygen in your blood during the operation. This sensor also measures your heartrate. Maxim makes this sensor for instance (MAX30102). http://media.digikey.com/pdf/Data%20Sheets/Maxim%20PDFs/MAXREFDES117_Web.pdf
