CCS811 Gas Sensor Solution

Ultra-low power digital gas sensor for monitoring indoor air quality

 

The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor for monitoring indoor air quality (IAQ) including a wide range of Volatile Organic Compounds (VOC), a microcontroller unit (MCU), an Analog-to-Digital converter (ADC), and an I²C interface.

Key Features

  • Integrated MCU
  • On-board processing
  • Standard digital interface
  • Optimised low-power modes
  • IAQ threshold alarms
  • Programmable baseline
  • 2.7 x 4.0mm LGA package
  • Low component count
  • Proven technology platform

Key Benefits

  • Managing the sensor drive modes and measurements while detecting VOCs
  • Provides indication of IAQ levels with no host intervention
  • Simple development for faster time to market
  • Extend battery life in portable applications
  • No need for continuous monitoring in software, reduces host power/processing
  • Stable and predictable behaviour regardless of air quality at power up
  • Small form-factor designs
  • Saves up to 60% in PCB footprint
  • Designed for high volume and reliability (> 5 year lifetime)
