CO2‚ Humidity and Temperature Sensor - SCD30

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.

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.
