Adafruit SCD30 NDIR CO2 Temperature and Humidity Sensor ...

The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means it''s a lot bigger and more expensive, but it is the real thing.
