This is the progress to date on creating a wireless Bluetooth ID sensor modules. The finished system will be used to deliver useful information based upon who is near a particular sensor. Potential applications include a system to determine who is currently in the office, and a signage system that provides personalized wayfinding information to travelers as they pass by.
The Bluetooth sensor is wired to a microcontroller that requests the discoverable Bluetooth IDs within 10 meters of the sensor. This information is then passed out of the sensor module via an XBee brand ZigBee radio to a base station. The current base station sends the IDs via serial to a computer, but the next version will use a Lantronix XPort to send them over the Internet to a server program.
