Fusing sensor systems: promises and problems Available to Purchase

By tradition, sensors are used to measure one desired parameter; all other parameters influencing the sensor are considered as interfering inputs, to be eliminated if possible. Hence most of existing sensors are specifically intended for measuring one parameter, e.g. temperature, and the ideal temperature sensor should be as immune to all other parameters as possible. True, we sometimes use primitive sensor fusion, e.g. when calculating heat flow by combining separate measurements of temperature difference and of fluid flow.
