1. A sensor for cable connection to a main control unit of an electrical domestic appliance, the sensor for cable connection comprising:
an electrical sensor circuit accommodated in a sensor housing with a plurality of at least two measuring sensors arranged in different branch circuits, each of which measuring sensors is designed to provide an electrical measuring signal, wherein the electrical sensor circuit has a first electrical contact element for plug connection to a cable plug and is able to output measurement information obtained via the first electrical contact element from the electrical measuring signals of each of the plurality of measuring sensors; and
an evaluation unit designed to receive electrical measuring signals from the at least two measuring sensors, wherein the electrical measuring signals that are received by the evaluation unit are used to control an output signal generator, wherein the output signal generator is adapted to generate an output signal which contains or represents the measurement information, wherein the output signal is a time-variable electric voltage or a time-variable electric current, wherein the output signal generator is adapted to output the output signal via the first electrical contact element, wherein the first electrical contact element is connected to a signal line in a cable, connecting the sensor for cable connection to the main control unit of the electrical domestic appliance, wherein the cable comprises a voltage supply line connected to a second electrical contact element of the sensor for cable connection, wherein the second electrical contact element serves at least as a voltage supply to the evaluation unit, wherein the output of measurement information by the evaluation unit is controllable via a time-varying voltage or current signal that is applied by the main control unit of the electrical domestic appliance to the voltage supply line.
