Wireless ECG Monitor Design Based on Raspberry Pi3 and AD8232 Microchip

Abstract

This paper describes the designing and the development of a wireless electrocardiogram (ECG) monitoring system. In general, health monitoring is an attractive research area, and the proposed systems in the literature are expanding exponentially. Although it is hard to choose adequate technologies and designs that satisfy the needs and fulfil the requirements, an efficient and practical low-cost system has been built. In this work, a remote study process of the recorded electrical activity of the heart using a WiFi Module is achieved. The presented model considers transmitting the detected signals in real-time via wireless communication networks and then analyzing the results on Raspberry Pi 3. The received data will be stored, and digital filtering will be performed. While storing the data on files, the Raspberry Pi3 runs the Plotly streaming program simultaneously, which reads the data received with 10-bit precision and streams it in real-time for QRS detection processing. Then, detected and analyzed data will be exhibited on a website aligned with daily health advice based on patient health states. The webpage has been generated with Python based on the bokeh library, and it has been streamed using the Apache http web server. A portable ECG monitor system that complies with medical equipment design and electrical safety has been realized in this work.
