IoT-Based ECG Monitoring System on Smartphones

This research introduces a monitoring system for Electrocardiogram (ECG) using a smartphone. The system uti-lizes an ESP32 microcontroller and an AD8232 sensor to acquire ECG signals and transmit them via Bluetooth to a smartphone app. The accuracy and reliability of the system were compared with a traditional ECG machine. The findings suggest that this system has the potential to offer real-time monitoring for cardiac arrhythmias. A review of existing literature was conducted to examine the state of smartphone-based ECG monitoring system, including the challenges and limitations associated with this technology. The results indicate that this proposed system is a solution for easy accessible and convenient ECG monitoring, which could potentially bring significant improvements in health-care provision by enabling early detection of cardiac arrhythmias and providing a convenient mean for continuous monitoring of heart activity. This study aims to provide an overview of the design, implementation and evaluation of a smartphone-based ECG monitoring system while demonstrating its feasibility for real-time heart activity monitoring.
