A sensor device and its application in e-health

Abstract

The projects Self-help through a mobile ICT tool and The ICT Lifestyle and Health Motivation Project at the Norwegian Centre for Telemedicine (NST) have designed and built a prototype smart sensor system. Just days before the hand-in of this thesis, the second version of the prototype was ready for testing. Central for this thesis is the hardware and software debugging process of this first prototype. The result of this process is a number of suggestions for changes in the microcontroller’s software and the hardware generally. The suggestion for changes does not introduce any new features, but rather tries to direct the functionality towards the project group’s intention. The main suggestions involve how to avoid loss of data, and also let the user take charge over when the step-counter should report to the mobile base. The thesis starts with an introduction to the main project and a revision of similar projects. The direction then changes towards the theory and tools necessary to perform the intended task are presented. A somewhat large part is devoted to design of movement sensors. As a part of this there were done some tests. The results of some of these plus suggestions for some new are presented. As wireless communication carrier the project group has chosen Bluetooth. The thesis gives a revision of the module chosen plus some alternatives. In addition there is also some suggestions regarding the setup of the module.
