  • Bifunctional environment sensor
    Patent number: 4649364
    Abstract: An environment sensor includes an insulating base board, a first electrode made of a material which can provide an electrical indication of the value of a first physical quantity and formed on the insulating base board, a second electrode formed of electrically conducting material and formed on the insulating base board, and a mass of metal oxide semiconductor material which can provide an electrical indication of the value of a second physical quantity, layered on the base board over the first and second electrodes. Thus, the first electrode by itself constitutes a sensor subsystem which can sense the value of the first physical quantity, which may preferably be temperature, while the first and second electrodes together with the mass of metal oxide semiconductor material constitute a sensor subsystem which can sense the value of the second physical quantity, which may preferably be humidity.
