ZIGBEE BASED WIRELESS PATIENT TEMPERATURE AND PULSE MONITORING SYSTEM

Abstract

Many health monitoring systems exist due to the fact that health monitoring is paramount as it is useful to indicate life in the human body. Despite the many systems that exist, life is still being threatened as low sensitivity and accuracy devices are still being used. Also, many health institutions in developing countries like Nigeria are still faced with the challenge of remotely monitoring unstable and critical patients. This project describes the design and implementation of a human pulse rate and temperature monitoring device based on zigbee technology. It presents the use of high sensitivity and accuracy devices such as the thermistor for temperature monitoring and the use of disposable ECG electrodes for pulse rate monitoring. The system consists basically of the transmitting and the receiving units. Zigbee technology is used for wireless transmission and results are displayed via a Liquid Crystal Display (LCD). Subsequently, as a means to measure performance, three samples collected from available results were used and compared with the results obtained from project. The results show 87.2%, 89.5% and 88.1% accuracy for temperature measurement and 98.39%, 97.23% and 98.58% accuracy in pulse rate measurement for the three samples. The device remotely measures human temperature and pulse in real time and can be used in especially small scale hospitals and clinical environments. The device is also user friendly and cost effective.
