Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

Jul 25, 2021· The SCD-30 is an NDIR sensor, 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 - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
