Abstract: A condition monitoring system for monitoring a condition of a piece of machinery includes: one or more sensor motes installable proximate to a piece of machinery, each of the one or more sensor motes including a housing, a microprocessor, an onboard precision clock in electronic communication with the microprocessor, and an antenna in electronic communication with the microprocessor; one or more sensor devices in wired electronic communication with the microprocessor of one of the one or more sensor motes, the one or more sensor devices in sensory contact with the piece of machinery; a gateway device including a microprocessor and one or more antennas in communication with the microprocessor. When the gateway device is within a wireless range of the one or more sensor motes the gateway device receives time stamped sensor data transmitted to the gateway device from the one or more sensor motes.
