An electronic system and method for detecting carbon dioxide is provided, using a nanostructure sensing device (CO2 sensor). The CO2 sensor is made up of a substrate and a nanostructure disposed over the substrate. The nanostructure may comprise a carbon nanotube, or a network of nanotubes. Two conductive elements are disposed over the substrate and electrically connected to the nanotube. A gate electrode may be positioned opposite the nanostructure. A functionalization material reactive with carbon dioxide is disposed on CO2 sensor, and in particular, on the nanotube. The CO2 sensor may be connected to an electrical circuit, which will respond to changes in CO2 concentration in the ambient sensor environment.
