20210725· 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 ...
20190720· In this project, we recorded CO2 and O2 data from six Sensirion SCD30 and GroveME2O2 sensors using Arduino MEGA. While the ME2O2 produce analog output, the SCD30 communicate via the I2C interface. Each SCD30 sensor has the same permanent I2C address, therefore, we use TCA9548A I2C multiplexer to read multiple SCD30. The realtime data was displayed using low power …

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won''t operate properly.
CO2 = 410*ppm* (Rs/f_RH_T / Rs410/f_RH_T_410)^b Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor …
