Abstract

A power and environmental monitoring system includes a power distribution unit, a power monitoring system including an internal sensor for monitoring power consumption characteristics of power supplied to equipment coupled with the power distribution unit, an environmental monitoring system including an internal sensor for monitoring environmental characteristics in a physical environment occupied by the power and environmental monitoring system, and a network connection. The power monitoring system and the environmental monitoring system share a common interface accessible via the network connection. The power distribution unit includes an I/O port for connecting an external sensor, and the environmental monitoring system is configured for receiving environmental characteristics sensed by the external sensor. The common interface comprises a series of Web pages for displaying characteristics sensed by the power monitoring system and the environmental monitoring system. An alarm is provided for alerting an operator that a characteristic has reached an alarm threshold.
