Through programming, it can measure the concentration of TVOC (Total Volatile Organic Compounds) and eCO2 (equivalent CO2), with a typical measurement accuracy of 15% within the measurement range. The SGP30 readings are internally calibrated for long-term stability. The SGP30 communicates via the I2C protocol and features on-chip humidity compensation, which can be enabled by connecting an external humidity sensor. For precise results, calibration based on a known measurement source is required, and the SGP30 has built-in calibration functionality.
