METAL-THEFT DETECTION DEVICE

摘要

A metal-theft detection device includes a first sensing terminal configured to be electrically coupled with an earth wire of a mains electricity circuit, a second sensing terminal configured to be electrically coupled with a neutral wire of the mains electricity circuit, a wireless communications module, and circuitry configured to measure a resistance of a conductive path connected between the first and second sensing terminals, and to cause the wireless communications module to transmit a wireless message based on the measured resistance.
