This SparkFun CO2 Humidity and Temperature Sensor features the next-generation SCD40 photoacoustic CO2 sensor for high-accuracy environmental readings. The SCD40 uses Sensirion's PASens® photoacoustic measurement system that combines narrow-band IR light and a microphone inside the sensing package capable of detecting concentrations from 0 to 40000 ppm with high accuracy over 400-2000 ppm ±(50 ppm+5%). The SCD41 has an integrated temperature and humidity CMos® sensor to improve accuracy. For additional accuracy, the SCD40 also accepts ambient pressure readings! All this functionality comes in our standard 1in. x 1in. Qwiic form factor and will seamlessly integrate into your Qwiic-based projects. However, we still routed the I2C signals out to a set of 0.1in.-spaced pins for users who prefer a soldered connection.

The SCD40 includes an automatic self-calibration routine to automatically adjust to its sensing environment over a seven-day calibration period. For best results, Sensirion recommends taking continuous readings for at least one hour a day of 'fresh air' for the calibration period to complete.

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.
