Carbon dioxide measurement

Carbon dioxide measurement involves detecting and quantifying the amount of CO₂ gas in the air or environment. This is usually done with specialized sensors that identify CO₂ molecules using methods like infrared spectroscopy or chemical absorption. Accurate measurement helps monitor air quality, track environmental changes, and manage indoor ventilation. The results are typically expressed in parts per million (ppm), indicating how much CO₂ is present relative to other air components. Reliable measurements are essential for ensuring healthy indoor spaces, assessing pollution levels, and studying climate impacts.
