The SCD30 from Sensirion is a high-quality 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.

SparkFun has 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 downloaded here. SparkFun recommends using a Qwiic Breadboard Cable to connect the SCD30 to a Qwiic compatible board. The YeLLow wire goes in the SCL pin. The SCD30 also supports a serial interface but SparkFun hasn’t worked with it.

The CO₂ sensor works very well and for additional accuracy, the SCD30 accepts ambient pressure readings. We recommend using the SCD30 in conjunction with the Qwiic Pressure Sensor - MS5637 or the Qwiic Environmental Sensor - BME680 to obtain the current barometric pressure.

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.

SparkFun does not plan to regularly stock all SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting-edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products.
