CJMCU-811 CCS811 Indoor air quality monitoring digital gas sensor is an ultra-low-power digital gas sensor that integrates a CCS801 sensor and an 8-bit MCU with an analog-to-digital converter (ADC) to detect indoor air quality, including carbon monoxide (CO) and a wide range of Volatile Organic Compounds (VOCs).

The sensor offers simple and easy interface through I2C. Libraries, circuit and sample codes are available for Arduino, Raspberry pi, ESP32, etc. This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones. 

This sensor has low power consumption, it can work in battery work equipment. It integrates CCS801 sensor and 8-bits MCUs (with analog-to-digital converters (ADCs)), can be used to run the first-level algorithm. Meantime, it integrates 12-bits ADC, so that can be applied for reading of sensor and digitized conversions. The sensor can output I2C signal directly, make directly communication with main system.

The sensor can be used for detecting air quality indoor, including CO2, extensive volatile organic compound gases (VOCs) and metal oxide gases (MOX).


  • Ultra-low power consumption can be used in battery-operated equipment
  • High sensitivity, fast heating
  • The intelligent algorithm calculates TVOC / eCO2 values
  • Output I2C signal, direct communication with the main system
  • Metal oxide (MOX) sensors for monitoring indoor air quality
  • An 8-bit MCU is integrated to run the first-level algorithm
  • Integrated 12-bit ADC for sensor readings and digitized conversions
  • I2C slave interface can be directly connected to the host system
  • Reset / interrupt control
  • Digital output: Active low (When it outputs a low-level signal, the indicator LED will be on)
  • Analog output: Two Range Options: 0 to 2V or 0V to 4V. The default is 0V to 2V DC


  • It can be used for HVAC applications to monitor the quality of air.
  • It is used to monitor fermentation, aerobic respiration, photosynthesis and other carbon dioxide consuming or producing processes
  • Smartphones
  • Wearables
  • Home and Building automation

Package includes:

  • 1 x CCS811  Air Quality Digital Gas Sensor
