1. An arrangement, comprising:
- a plurality of MEMs sensors, each sensor operably coupled to measure a parameter of a refrigeration system, each sensor coupled to one of a plurality of wireless transmission devices;
a processing circuit configured to receive first information based on the parameters of the refrigeration system from the wireless transmission devices, the processing circuit further operable to,compare the first information to one or more reference values; and
generate a first message conditionally, based on the result of the comparison.

Abstract
A method and/or apparatus determines whether a refrigeration (or other cooling) related system is operating within normal parameters by comparing reference data derived from ideal or normal conditions within the system. Data regarding the actual operating parameters of the system is provided via a set of microsystem sensors disposed throughout the refrigeration or cooling system. The sensors are in some embodiments wireless, and in some advantageous embodiments includes MEMs sensors.
