1. A sensor monitor for use with a sensor and for use with a data aggregator coupled to a wireless communications link, the sensor monitor comprising:
- a wireless communications module;
a controller functionally coupled to the wireless communications module, the controller operable to;
receive sensor data from the sensor,sample the received sensor data to generate a plurality of sensor data points,communicate the plurality of sensor data points to the wireless communications module for transmission to the data aggregator,compare the plurality of sensor data points to an alarm condition algorithm,activate an alarm condition when the plurality of sensor data points satisfies the alarm condition algorithm; and
whereinthe wireless communications module is operable totransmit sensor data points received by the wireless communications module to the data aggregator via the wireless communications link, andtransmit a received alarm to the data aggregator via the wireless communications link.

Abstract
An automatic inspection system includes intelligent sensor monitors. A sensor monitor receives input from at least one sensor. The sensor monitor conserves power and communications link bandwidth by transmitting data to an aggregator or server only when relevant to rules of the inspection system or when prompted by the inspection system for data. The sensor monitor also provides an alarm when the sensed data indicates an alarm condition, and the alarm provided is indicative of the alarm condition.
