CO2 and RH/T Sensor - SCD30

The SCD30 from Sensirion is a high quality Nondispersive Infrared (NDIR) based CO₂ sensor capable of measuring 0 - 40'000 ppm an accuracy of ± (30 ppm + 3% MV) at 25 °C, 400 - 10'000 ppm. Along with the NDIR measurement technology for CO2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module.

Carbon dioxide (CO₂) is a key indicator of indoor air quality. Houses have be-come increasingly energy efficient, but the air quality can deteriorate rapidly. Active ventilation is needed to maintain a comfortable and healthy indoor environment. Sensirion’s SCD30 offers accurate and stable CO₂, temperature and humidity monitoring.

Sparkfun has written an Arduino library to make reading the CO₂, humidity, and temperature very easy.

Note: This product requires soldering. After soldering, you cannot return the product. You can test the Qwiic version (see below) without soldering.
