The SCD30 from Sensirion is a high quality [NDIR](https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor) 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.

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'. We recommend using a [Qwiic Breadboard Cable](https://www.sparkfun.com/products/14425) to connect the SCD30 to a Qwiic compatible board. The Ye*LL*ow wire goes in the SC*L* pin. The SCD30 also supports a serial interface but we haven't worked with it.
