This job will be an extension of the wireless sensor research we have already completed. It will have two main parts: The first is to create and test the possibility of a short range proximity sensor using xbee transmitters. The second is to build a short range proximity system using a hall sensor and magnet(s) (worn on the neck and and wrist respectively) that will activate a third remote alarm when the Hall sensor and magnet come within range of each other. These two projects are described in more detail below.
1) Build and test of xbee short range proximity sensor. This project will test the possibility of using xbee wireless sensors for short-range proximity detection. The goal will be to build a prototype which tests the quality of proximity detection (and range) it is possible to achieve. While xbee transmitters are usually designed to transmit over large distances (100m+) we hope to tune down this range significantly, and if successful, it would be desirable to be able to de...
