New Products 1/6/2021 Featuring Adafruit SCD-30 -NDIR CO2 …

08/01/2021· 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 it’s a lot bigger and more expensive, but it is the real ...

White line is CO2 measured by a different sensor sitting next to my test rig. Notice how noisy the orange and red traces are compared to the white. As you can see, this graph covers some night-time where there is no activity in the building. In terms of CO2, it either over-reads or under-reads compared to the 'real' amount of CO2. I *am* compensating for temperature and RH% in my test setup (SHT21 module you …
