Determination of carbon dioxide in ambient air

Study of the sensory properties of pyrolyzed polyacrylonitrile in relation to carbon dioxide was carried out. This article describes sensors for determining carbon dioxide and their principles of operation. Carbon dioxide sensors are devices that detect and measure the concentration of CO2 in the atmosphere or in a specific environment. These sensors are used in a wide variety of fields, such as monitoring air quality inside buildings, controlling CO2 emissions in industrial processes, and measuring atmospheric CO2 levels for climate research.
