Abstract
A sensor system has a least one voltage generator for conversion of non-electrical energy to electrical energy. At least one energy store is connected downstream from the voltage generator. At least one voltage converter is connected to the energy store such that its output signal is suitable for operation of a processor controller. At least one sensor is provided, and at least one transmitter enables wire-free transmission of transmission messages produced by the processor controller and containing at least one measured value from the at least one sensor. A timer circuit is triggered as a function of a voltage level of the at least one energy store, and activates the sensor system to transmit at least one transmission message after a specific time interval.
