Adafruit STCC4 and SHT41 - CO2, Temperature & Humidity Sensor - STEMMA QT / Qwiic
Adafruit Industries, LLC mail
The STCC4 is a tiny (4 x 3 x 1.2mm) sensor that can measure CO₂ gas and fit in just about any enclosure. It uses thermal conductivity (TC) instead of NDIR or photoacoustic measurements. TC is based on the inherent thermal conductivity of all gases. With a thorough understanding of the gas composition in ambient environments, subtle changes in gas concentrations can be detected. The measurement principle is based on heating the air within a measurement cavity and sensing the heat transfer with a temperature sensor. For more details check out the EYE ON NPI video we did on this sensor!
