The CCS811 is a low-power digital gas sensor module designed for indoor air quality monitoring applications. It measures Total Volatile Organic Compounds (TVOC) and provides an equivalent CO₂ (eCO₂) value, which is calculated using an onboard algorithm based on VOC gas levels, not direct CO₂ sensing.
The module integrates an internal processing engine and ADC, enabling intelligent gas trend analysis with minimal external computation. It communicates via the I2C interface, making it easy to integrate into microcontroller-based systems.
This sensor is well-suited for smart home devices, IoT air quality monitors, HVAC control systems, and battery-powered environmental sensing applications.
