Humidity and Temperature Sensor - SCD40 (Qwiic)","description":"\u003cp\u003eThe SCD40 from Sensirion is a high quality Photoacoustic based CO? sensor capable of detecting 0 to 40000ppm with the best accuracy over 400-2000ppm ±(40ppm+5%). In order to improve accuracy the SCD40 has integrated temperature and humidity sensing built-in. For additional accuracy the SCD40 also accepts ambient pressure readings!\u003c\/p\u003e \u003cp\u003eWe've written an Arduino library to make reading the CO?, 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.\u003c\/p\u003e \u003cp\u003eNote: The SCD40 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.\u003c\/p\u003e \u003cdiv class=\"alert alert-warning\"\u003e\n\u003cb\u003eExperimental Product:\u003c\/b\u003e \u003ca href=\"https:\/\/www.sparkfun.com\/sparkx\"\u003eSparkX\u003c\/a\u003e products are rapidly produced to bring you the most cutting edge technology as it becomes available.
