The Unit Mini TVOC/eCO2 is a digital multi-pixel gas sensor unit with an integrated SGP30, primarily designed to measure various VOCs (Volatile Organic Compounds) and H2 in the air. 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… (M5Stack U088)
