CCS811 Air Quality Sensor Module (eCO2 and TVOC Digital Gas Sensor)

The CCS811 Air Quality Sensor Module is a digital air quality sensor designed to measure Total Volatile Organic Compounds (TVOC) and equivalent Carbon Dioxide (eCO2) levels in indoor environments. Based on the CCS811 gas sensor IC, it uses advanced metal oxide sensing technology and an integrated processing algorithm to provide accurate digital air quality data. The module communicates through an I2C interface, making it easy to integrate with Arduino, ESP32, STM32, Raspberry Pi, and other embedded platforms for environmental monitoring and IoT applications.

Note: The CCS811 does not directly measure Carbon Monoxide (CO). It measures TVOC and calculates equivalent CO2 (eCO2).
