Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extract oxygen from and then breathe out carbon dioxide. CO2 is essential for life on this planet we call Earth - us and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our planet. The SCD-30 is an NDIR sensor (), which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) position 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 experiments, air quality and ventilation studies and more. ©Adafruit...
