The SCD41 from Sensirion is a high quality Photoacoustic based CO2 sensor capable of detecting 0 to 40000ppm with high accuracy over 400-5000ppm ±(40ppm+5%). In order to improve accuracy the SCD41 has integrated temperature and humidity sensing built-in. For additional accuracy the SCD41 also accepts ambient pressure readings!

We've written an Arduino library to make reading the CO2, humidity, and temperature very easy. It can be downloaded through the Arduino Library manager: search for 'SparkFun SCD4x' or it can be found in the Documents tab above.

Note: The SCD41 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour a day of 'fresh air' for self-calibration to complete.
