CCS801: Ultra-Low Power Gas Sensor for Monitoring Indoor Air Quality

The CCS801 is an ultra-low power MOX multi-gas sensor for monitoring indoor air quality including Carbon Dioxide (CO) and a wide range of Volatile Organic Compounds (VOCs) such as Ethanol. CCS801 can be used as an equivalent carbon dioxide (eCO2) sensor to represent eCO2 levels in real world environments, where the main source of VOCs is from humans.
