1. A system for monitoring a machine, comprising:

  • a first sensor comprising a first processor;

    a second sensor comprising a second processor; and

    at least one communication trunk in communication with the first sensor and the second sensor, and operable to communicate sensor data between each of the first processor and the second processor;

    wherein the first sensor and the second sensor are operable to generate or detect sensor data associated with at least one machine condition; and

    wherein at least one of the first processor or the second processor is operable to;

    analyze sensor data generated or detected by each of the first sensor and the second sensor;

    aggregate the received sensor data;

    perform at least one of frequency domain analysis, a time domain analysis, or a filtered domain analysis on the sensor data; and

    determine at least one machine fault based at least in part on the analyzed sensor data, wherein the at least one machine fault relates to a physical condition of the machine.
