Patent ID: 7230532

Claim:
A sensor system (S, S′) comprising: at 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, to be triggered as a function of a voltage level of the at least one energy store ( 2 ) to activate the sensor system (S), a specific time interval after being triggered, in order to transmit at least one transmission message.
