Abstract

A monitoring device is disclosed that is configured to monitor conditions within an electrical enclosure containing electrical equipment. The monitoring device comprises a support configured to couple to an interior surface of the electrical enclosure. The support is configured to hold and electrically couple a plurality of sensors, at least two RF antennas, at least one processor in communication with the plurality of sensors and the at least two RF antennas, and a power connection configured to receive electrical and Ethernet input. The at least one processor is configured to receive and analyze data obtained from the plurality of sensors and the at least two RF antennas pertaining to a plurality of conditions inside the electrical enclosure. The at least one processor is configured to detect a potential electrical equipment failure based on the received an analyzed data.
