SCD30 - CO₂ Humidity and Temperature Sensor [SEN-15112] - (AD52949)

Description:

The Sensirion SCD30 is a high-quality non-dispersive infrared (NDIR)-based CO₂ sensor capable of detecting 400 to 10,000 ppm with an accuracy of ±(30 ppm + 3%). To improve accuracy, the SCD30 features built-in temperature and humidity sensors, as well as commands to set the current altitude. For added accuracy, the SCD30 also accepts ambient pressure readings.

We've written an Arduino library to make it easy to read CO₂, humidity, and temperature. It can be downloaded through the Arduino library manager: search for 'SparkFun SCD30' or found in the Documents tab.

The SCD30 temperature and humidity sensor can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis data logging system. No programming, soldering, or setup required!

Note: The SCD30 has an automatic self-calibration routine. Sensirion recommends 7 days of continuous readings with at least 1 hour of fresh air per day to complete the self-calibration.
