The CCS811 is a gas sensor that monitors the air quality and can measure a large number of volatile organic compounds (VOCs).
The sensor data can be converted to a total volatile organic compound (TVOC) or carbon dioxide equivalent (eCO2) level.
The module has a metal oxide (MOX) sensor and also the option to connect a NTC for temperature measurement.
NOTE: A single burn-in of 48 hours and a warm-up time of 20 minutes is recommended before valid data can be expected.
