Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

2021-08-13· The SCD-30 is an NDIR sensor (https:///CQ6), which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration (https:///PF7) - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect ...
