Implementation of ZigBEE (IEEE 802.15.4) Based Wireless ECG Measurement System

Abstract

This study presents a realization of a ZigBEE based wireless ECG system for remotely monitoring the patient's electrocardiogram (ECG) via wireless heart sensor (AD8232). The presented wireless ECG system is composed of hardware such as Arduino micro-controller connected to the electrodes on the patient, personal laptop, tablet PC, smart phone etc. for ECG signal monitoring, AD8232 sensor for measuring heart rate, ZigBEE transceiver (XBee S2C) for wireless transmission of ECG signal, and software such as Serial Plot or Arduino Serial Plotter. The results from the tests show that the system designed over a single node can work seamlessly in an open area of approximately 20 to 100 meters and take ECG measurements wirelessly. Additionally, the obtained results from the tests show that the ECG measurements can be taken wirelessly within a range of 20 to 80 meters when the obstacles are also placed between ZigBEE transmitter and receiver.
