Abstract

A monitoring system is provided that allows for monitoring and reporting of operational parameters for processes and devices in a subterranean environment. The system includes a plurality of interface devices coupled to sensors at a desired process or device. The interface devices transmit the measured data to a coordinator device through a personal area network. The coordinator device aggregates data from multiple interface devices and transmits the data to a remote service through a communications network.
