The CCS811 is an ultralow power digital gas sensor for monitoring indoor air quality. It appears what they accomplished is integration of a metaloxide gas sensor into a tiny package so it uses very little power and has a fast response. For example, the wellknown MQ135 typically uses 750 mW just for heating the sensitive MOX layer. The datasheet can be found here. It measures volatile ...

Formaldehyde and volatile organic compounds (VOCs) are major indoor pollutants with multiple origins. Standard methods exist to measure them that require analytical expertise and provide, at best, an average value of their concentrations. There is a need to monitor them continuously during periods of several days, weeks, or even months.

sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. This sensor is not well supported on Raspberry Pi. This is because it uses I2C clock ...
