Abstract: An infrared temperature monitoring system for measuring the temperature of areas or subsystems of an aircraft is provided. The system includes a plurality of infrared sensors each configured for non-contact measurement of temperature associated with the areas or subsystems of the aircraft. Each of the plurality of infrared sensors has a unique node address and outputs an associated sensor signal. A temperature processing unit receives the sensor signal from each of the plurality of infrared sensors and analyzes the sensor signals based at least in part on the unique node address and outputting an interface signal. An interface system receives the interface signal from the temperature processing unit and outputs a control signal.
