Abstract
A self-calibrating carbon dioxide sensor that includes a carbon dioxide detector and a carbon dioxide gas generator. In some embodiments, the carbon dioxide gas generator includes a heating element and a carbon dioxide gas releasing solid material in thermal communication with the heating element. The carbon dioxide gas releasing solid material releases carbon dioxide when heated by the heating element. Methods of calibrating a self-calibrating carbon dioxide sensor are also disclosed.
