IoT Based ICU Patient Monitoring System

This project introduces a wearable, low-power, real-time remote bio-signal monitoring system built on Internet of Things (IoT) technology. It represents a significant advancement in the field of remote health monitoring. As the number of people requiring healthcare increases year by year, traditional monitoring systems that require in-person visits to hospitals are becoming increasingly inefficient, especially for patients with critical or unstable conditions. IoT and modern electronic devices offer effective alternatives to address this challenge. In this implementation, a mobile application serves as the IoT platform to remotely monitor live ECG signals, heart rate, SpO₂, and body temperature. These signals are measured and processed using a microcontroller-based device (Arduino). The main contribution of this work is to transmit ECG data to a designated smartphone, which allows doctors to remotely monitor patients’ cardiac activity and detect cardiac conditions before they escalate. The monitoring results are displayed on both smartphones and personal computers.
