This is a CircuitPython driver for the Sensirion SGP30 air quality sensor, it can provide CO2eq (equivalent CO2) and TVOC (Total Volatile Organic Compounds) with a simple I2C interface
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
