Wireless technologies which are the most important development areas in the twenty-first century and Wireless Body Sensor Networks which are developed for use in health care continues to be the focus on attention of researchers. Wireless Body Sensor Networks are used for monitoring health signals such as body temperature, heart pulse, EEG, and ECG of the people who are old, chronic illness or weak. In this paper, a health monitoring system is monitored via the Internet is presented. Implemented system consists of two parts: hardware and software. In the hardware part, body temperature and heart pulses of the patient are collected by the designed embedded system. And the system sends the data to health center over wireless sensor networks. And software part is a web based monitoring interface which accomplish to visualization and analysis of the collected data from the patient using MATLAB Builder NE and Web Figure.
