The CCS811 Carbon Monoxide Gas Sensor is a digital gas sensor solution equipped with an I2C interface, designed to detect a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. Volatile Organic Compounds (VOCs), including carbon monoxide, are common pollutants and sensory irritants found in various sources such as construction materials, machinery, and human activities like smoking or breathing.

This sensor offers a simple and straightforward interface through I2C, with available libraries, circuit diagrams, and sample codes for popular platforms like Arduino, Raspberry Pi, and ESP32. It is ideal for indoor air quality monitoring applications in personal devices such as watches and phones. The CCS811 sensor integrates a CCS801-bit sensor and MCU with an analog-to-digital converter (ADC), ensuring accurate detection of indoor air quality while operating on ultra-low power.
