Abstract

A distributed sensor system includes a plug-in attachment, the plug-in attachment having a memory and at least one sensor; a modular node, the plug-in attachment being configured to connect to the modular node, the modular node being configured to read the memory and receive sensor data from the at least one sensor; a network, the network being connected to the modular node; and a central processor, the central processor being connected to the network and being in communication with the modular node through the network. A method for configuring and using a distributed sensor system includes connecting at least one plug-in assembly to a modular node, the at least one plug-in assembly having a memory and at least one sensor, the memory containing configuration data; connecting the modular node and a central processor to a network; configuring the modular node via the network; the modular node retrieving the configuration data and sending the configuration data via the network to the central processor; the modular node receiving sensor data from the at least one sensor, the modular node transmitting the sensor data via the network to the central processor.
