Wireless Sensor Device For Health Monitoring, Using ZigBee Technology

In this project, we develop a portable real-time wireless health
monitoring system. Goal of the project is to monitor patient's heart rate. The
system was designed and implemented using ZigBee wireless technologies. All
data will be transferred within a group of wireless network to database computer
system. The sensor modules were designed for low power operation so that it
can last long. This project is divided into two phase which is sensor design
phase and transmission phase. In the first phase, sensor unit consists of two
types of LEDs and photodiode that is facing to a patient's fingertip and
microcontroller unit for interacting with ZigBee module. Second phase involve
ZigBee module to communicate with heart rate sensor. ZigBee module gets all
commands from microcontroller unit and it works on both transmitting and
receiving process. Throughput from ZigBee receiver will be displayed at
computer for monitoring purpose. This method can be developed into a
noninvasive technique to measure body temperature and blood pressure.
