A gas sensor comprising an electrolytic cell having detecting and reference electrodes connected by a solid electrolyte. In a first embodiment, both electrodes comprise Ag2CO3 and Ag4RbI5, and the electrolyte is Ag4RbI5, the reference electrode being in contact with a reference gas. In a second embodiment, the reference electrode is a silver electrode and no reference gas is needed. The sensor is operable at room temperature to measure CO2 concentrations, and is relatively unaffected by water vapor.
