CO2 Humidity and Temperature Sensor - SCD30

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.
