1. A sensor system (S, S′

  • ) comprising;

    a least one voltage generator (1, 11, 12, 13) for conversion of non-electrical energy to electrical energy, at least one energy store (2) coupled to the voltage generator (1, 11, 12, 13), a processor controller (4), at least one voltage converter (3) having an input coupled to the energy store (2) and an output coupled to said processor controller (4), at least one sensor (7, 71) coupled to said processor controller, at least one wire free transmitter (5) coupled to an output of said processor controller for wire-free transmission of transmission messages from said processor controller (4) which contain at least one measured value from the at least one sensor (7, 71), wherein a timer circuit (6) is provided, which can be triggered as a function of a voltage level of the at least one energy store (2), and which activates the sensor system (S) in order to transmit at least one transmission message after a specific time interval.
