Beschreibung
Zusammenfassung:	The present invention comprises: a power supply circuit that generates electric power from a first induced current obtained through electromagnetic induction coupling with an electric wire; a processor that operates with the electric power supplied from the power supply circuit; a current sensor that operates with the electric power, and measures the current flowing through the electric wire; an activation control circuit that activates the processor in accordance with the magnitude of the electric power generated by the power supply circuit; and a first circuit that is activated by the processor. The processor activates the current sensor in response to being activated by the activation control circuit, and activates the first circuit on the basis of the result of measurement of the current by the current sensor.
