CJMCU-811 CCS811 Monitoring Indoor Air Quality Digital Gas Sensor – CO ,VOCS

The CJMCU-811 CCS811 Indoor air quality monitoring digital gas sensor is an ultra-low-power 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).

  Features:  

• Ultra-low power consumption suitable for battery-operated equipment
• High sensitivity and fast heating
• Intelligent algorithm calculates TVOC / eCO2 values
• Outputs I2C signal for direct communication with the main system
• Metal oxide (MOX) sensors for monitoring indoor air quality
• Integrated 8-bit MCU for running the first-level algorithm
• Integrated 12-bit ADC for sensor readings and digitized conversions
• I2C slave interface for direct connection to the host system
• Reset / interrupt control
• Digital output: Active low (indicator LED on when low-level signal is output)
• Analog output: Two Range Options: 0 to 2V or 0V to 4V (default is 0V to 2V DC)

  Applications:  

• HVAC applications for air quality monitoring
• Monitoring processes such as fermentation, aerobic respiration, and photosynthesis
• Integration into smartphones, wearables, and home/building automation systems

  Package includes:  

• 1 x CCS811 Air Quality Digital Gas Sensor

This sensor is ideal for indoor air quality monitoring in various applications, offering a simple interface through I2C for easy integration with microcontrollers like Arduino, Raspberry Pi, and ESP32.
