Gas Sensors

Gas sensors play a central role in modern environmental and air quality monitoring. In particular, sensors for CO₂, TVOC (total volatile organic compounds), and NOx (nitrogen oxides) provide important data for assessing indoor and outdoor air quality.

CO₂ serves as an indicator of air exchange and indoor comfort, while TVOC indicates pollutant levels resulting from materials or activities. NOx, on the other hand, is primarily produced during combustion processes and is a significant factor in environmental and health risks.

Through precise measurement and rapid response, modern gas sensors enable smart ventilation systems and emissions control, and make a decisive contribution to energy efficiency and health protection.
