Health Monitoring System Using Wi-Fi as a Communication Medium on ARM7

Health monitoring systems become a hot topic and important research field today. Research on health monitoring were developed for many applications such as military, home care unit, hospital, sports training and emergency monitoring system. In this work, a portable real-time wireless health monitoring system is implemented using WI-FI and developed. The developed acquisition system is used for remote monitoring of patients’ temperature, heart rate and oxygen saturation in blood i.e. pulse oximetry, pH level of blood. This system allows the physician able to understand patient's scenario on the computer screen by wireless module. Here low cost, low power consumption and flexible network topology WI-FI wireless module is used to sense the remote patient data. All sensor data are transferred within a group of WI-FI wireless module. The goal is to demonstrate the possibilities offered by system-on-chip programmable devices in specific processing systems, where the costs make the use of specific integrated circuits unaffordable. The sensor unit consists of (1) temperature sensor (2)two types of LEDs and photodiode packed in Velcro strip that is facing to a patient’s fingertip for pulse oximetry and heart beat (3) three color LED with LDR for pH level (4) Microcontroller unit for interfacing with wireless module, processing all biomedical sensor data sending to base PC.
