Wireless sensor network (WSN) is an very important technology that is able to realize a vision of ambient intelligence. One of the application of Wireless Sensor Networks is Wireless E-Care Systems for monitoring the health of senior citizens. The idea is to use simple sensors that distributed in the old man/woman ’s outfit and home to provide home assistant/ nurse/ healthcare center/ relatives with a degree of ”understanding” of what he is doing, where he is, what is his health and activity state, what help he need, and what is happening around him.

Basically wireless sensor network consist of three parts: WSN, gateway and remote health-care centre. The purpose of this thesis is to develop a Graphical User Interface and Data Acquisition System for Home Health Care Using Tinyos-2.x Sensor Networks. This system is used for remote health-care centre.

This thesis presents design and implementation of a prototype of a system, which includes the following functions, collecting real-time data from tinyos-2.x sensor networks to a database; displaying nodes’ topology and deployment map at home in real time; plotting sampling values versus time in real time and replay time. dissemination parameters or commands to sensor networks.

Results of the experiments show this system is working well and reliable.
