System and method for controlling a plurality of sensors

Abstract

A system for controlling a plurality of sensors (24_1-24_8) includes a plurality of filters (28_1-28_8) each of which is configured to provide power transmitted at distinct frequencies to a corresponding sensor of the plurality of sensors to thereby activate the corresponding sensor and cause the corresponding sensor to generate a data signal. A power frequency controller (32) is configured to adjust a frequency of power from a power source and to transmit power at distinct frequencies at different points in time in order to activate each of the plurality of sensors at different times. A sensor controller (30) may be configured to receive the data signal from each of the sensors over a common conductor and on a common pin and may also act as the power source providing the power to the power frequency controller.
