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
