General Description
CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found indoors, with a microcontroller unit (MCU) and an Analog-to-Digital converter to monitor the local environment and provide an indication of the indoor air quality via an equivalent CO2 or TVOC output over a standard I2C digital interface.

This product suits for the following applications:
- Smartphones and accessories
- Air cleaners and purifiers
- Appliances (white goods)
- Home controllers
- Smart thermostats
