REMOTE POWER STATE DETECTOR

摘要

A system for remotely detecting a power state of an associated device comprising: an optical sensor configured to detect a light emitted from the associated device, wherein the light is indicative of the power state of the associated device; or electrical field (EF) sensor to detect the electrical field around power cord of associated device, wherein the electrical field is indicative of the power state of the associated device; a transmitter in communication with the optical or EF sensor; the transmitter configured to transmit a notification responsive to the optical sensor detecting the light or to the EF sensor detecting the electrical field; a receiver configured to receive the notification; and an alarm in communication with the receiver, the alarm configured to generate a warning responsive to the receiver receiving the notification.
