CCS811 Carbon Dioxide CO2 Temperature And Humidity Sensor VOCs Air quality Monitor Sensor Module
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources like construction materials (paint, carpet, etc.), machines (copiers, processors, etc.) and even people (breathing, smoking, etc.). This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.
The onboard CCS811 supports multiple measurement modes that have been optimized for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications.


  • Total Volatile Organic Compound (TVOC) sensing from 0 to 1,187 parts per billion
  • eCO2 sensing from 400 to 8,192 parts per million
  • Five Operating Modes
  • Integrated MCU
  • Onboard Processing
  • Standard I2C Digital Interface
  • Standard I2C Digital Interface
  • Optimized Low-Power Modes

  • Power supply: 3.3V
    CJMCU-811 a gas sensor chip system chip (SSoC) + temperature and humidity sensor, using low-power sensing technology to detect indoor volatile organic compounds (VOCs).
    CCS811 CJMCU8118 board schematic structure of the figure we can see that this is not a simple sensor, it has integrated MCU, the sensor has an onboard processing capability, without host intervention, can provide the equivalent level of carbon dioxide or total volatile organic compounds (TVOC) index. At the same time, with the use of separate gas sensors and MCU solutions, CCS811 can save equipment inventory costs as well as up to 60% of the total area of the board.
    The relative humidity is 2% (typical)
    Temperature accuracy of + 0.2 C (typical)
    Excellent stability under high humidity
    14 bit resolution
    Sleep mode current is 100nA
