Adafruit SGP30 TVOC/eCO2 Gas Sensor

· The sensor to sensor variation of SGP30 in terms of sensitivity is very good as each of them is calibrated. But the baseline has to be determined for each sensor individually during the first Operation. To make that easy, SGP lets you query the ''baseline calibration readings'' from the sensor with code like this: uint16_t TVOC_base, eCO2_base;
