M5Stack TVOC/eCO2 Gas Sensor Unit SGP30

The TVOC eCO2 Unit is a digital multi-gas sensor with integrated SGP30 from Sensirion. It primarily measures various VOCs (Volatile Organic Compounds) and H2 in the air. The sensor can be programmed to measure TVOC (Total Volatile Organic Compounds) and eCO2 (equivalent carbon dioxide measurement), thus assessing indoor air quality. The typical measuring accuracy is 15% within the measuring range. The SGP30's measurement value is internally calibrated, ensuring long-term stability. SGP30 uses the I2C communication protocol. If you want an accurate result, you have to calibrate the sensor against a known measurement source. Since the eCO2 is calculated based on the H2 concentration, it cannot fully replace pure CO2 sensors.
