SparkX STC31 Breakout (Qwiic) (SPX-18385)

An Arduino library for the STC3x family of CO₂ sensors from Sensirion. The STC31 uses Sensirion’s patented CMOSens® sensor technology to measure CO₂ concentrations up to 100%.

We've written this Arduino library to make reading the CO₂ concentration very easy. It can be downloaded through the Arduino Library manager: search for 'SparkFun STC3x'.

Library written by Paul Clark, based on the SCD30 library by Nathan Seidle (SparkFun).
