• Description
• The SCD30 from Sensirion is a high quality Nondispersive Infrared(NDIR)based CO2 sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in, as well as commands to set the current altitude. For additional accuracy the SCD30 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 SCD30' or it can be found in the

• tab above.
• The SCD30 Humidity and Temperature Sensor can also be automatically detected, scanned, configured, and logged using the OpenLog Artemis datalogger 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 a day of 'fresh air' for self-calibration to complete.
