Above is a system diagram for BlueWay, the Bluetooth presence detection system that we are building for the ITP Spring Show. There will be a total of six sensor modules which pass Bluetooth discovery information generated by a BlueSMiRF radio to an ZigBee mesh networking radio. All the remote ZigBee radios connect to one on a central base station, which passes all of their information via a secure TCP/IP Internet connection to a display system. The display system runs in Java, and connects to a database of the people’s names and pictures that are linked to their Bluetooth ID. These names and pictures are shown on a central display. Looking for someone? Check BlueWay to see where they are!
