Development of a Remote Physiological Index Monitoring System

In areas such as medical, military and physical exercise, often physiological indexes like temperature, humidity and motion are of great interest. In work, we developed a Wireless Biomedical Sensor Network (WBSN) which is able to wirelessly monitor temperature, humidity and acceleration of a sensor terminal. The designed a sensor network provides a low power, small size and easy-to-use package solution for physical activities monitoring. The system could be potentially used in hospitals, training camps, gyms, and many other places. The proposed system is designed to collect data from various sensors and then wirelessly transmits that data to a PC station. The PC station displays the real time sensor data onto a Graphic User Interface (GUI) and uploads the information to a MySQL database, which can be accessed by any device through internet. In the designed system, A PIC16 microcontroller is used as the control unit and low power Zigbee modules are implemented for data transmission. In addition, a MySQL database is developed on the remote server to store the data. The GUI used in this work is developed in Eclipse using Java language. The WBSN is able to sends signal at 250 Kbit/sec. With a 30m transmission range, the system has an overall current consumption about 25mA when powered by a 3.3V power supply. This shows great potential in indoor biomedical monitoring, physical training and military activities applications.
