Sciosense CCS811 (Gas Sensor)

The Sciosense CCS811 is a gas sensor designed for indoor air quality monitoring, capable of detecting a wide range of Volatile Organic Compounds (VOCs). When connected to a microcontroller, it provides a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over the I2C interface. The sensor utilises a 'standard' hot-plate MOX sensor, with a small microcontroller managing power to the plate, reading the analogue voltage, and offering an I2C interface for reading data. It can measure eCO2 concentrations within a range of 400 to 8192 parts per million (ppm), and TVOC concentrations within a range of 0 to 1187 parts per billion (ppb). The fact sheet states that it can detect Alcohols, Aldehydes, Ketones, Organic Acids, Amines, Aliphatic and Aromatic Hydrocarbons.
