Jul 25, 2021· 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 its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

May 06, 2021· Hi bobmehew, I''m a novice here too, but my understanding is that the SCD30 can communicate either through Modbus (Tx/Rx) or through I2C (SDA/SCL). The Sparkfun library uses the I2C mode and relies on the Wire library. So, yes you should be connecting to the SCL/SDA pins on the Arduino. You should also leave the SEL pin on the SCD30 floating.
