CCS811 CO2 eCO2 TVOC Air Quality Detection Sensor Module - I2C Interface
The CCS811 is a low-power digital gas sensor module for indoor air quality monitoring, measuring TVOC and providing an eCOâ‚‚ value via an onboard algorithm. It communicates via I2C, making it compatible with Arduino, Raspberry Pi, ESP32, and other 3.3V/5V microcontroller systems.
Features
- Measures Total Volatile Organic Compounds (TVOC) and provides an equivalent COâ‚‚ (eCOâ‚‚) value via onboard algorithm.
- Ultra-low power consumption with sleep/measurement modes, ideal for battery-powered IoT devices.
- Integrated MCU and ADC for onboard signal processing and intelligent gas trend analysis.
- Standard I2C digital interface with a default slave address of 0x5A for easy integration.
- Wide operating temperature range from -40°C to +85°C for robust environmental performance.

The CCS811 sensor module utilizes a Metal Oxide (MOX) sensing element to detect a broad range of volatile organic compounds (VOCs). The integrated microcontroller processes the raw sensor data, providing calibrated digital outputs for TVOC concentration in parts-per-billion (ppb) and an estimated COâ‚‚ (eCOâ‚‚) level, which is algorithmically derived from the VOC measurement.
Designed for low-power operation, the module supports multiple measurement modes and an interrupt-driven wake-up function, making it suitable for continuous monitoring in smart home, HVAC, and portable air quality applications. The sensor requires an initial warm-up and a recommended 24-48 hour burn-in period for optimal long-term stability and accuracy.
