Description This CJMCU-811 CCS811 air quality sensor module is a digital indoor air quality detector. It can detect volatile organic compounds and calculate equivalent carbon dioxide concentration. Compared with simple analog gas sensors, it outputs standardized eCO2 and TVOC data without complex calibration calculation on the main control side. It is widely used for home air quality monitors, fresh air linkage control, indoor environmental logging and gas detection teaching experiments.
