IoT-Based Smart Health Monitoring System for COVID-19 Patients

TLDR

IoT-based health monitoring systems can be highly beneficial for COVID‑19 patients and may save lives during the pandemic. The study aims to present a real‑time IoT health monitoring system that tracks body temperature, pulse rate, and oxygen saturation for COVID‑19 patients. The system employs an Arduino Uno platform with an LCD display and mobile‑app synchronization, and was tested on five human subjects. The system quickly stores data and demonstrates accuracy comparable to commercial devices.

Abstract

During the ongoing COVID-19 pandemic, Internet of Things- (IoT-) based health monitoring systems are potentially immensely beneficial for COVID-19 patients. This study presents an IoT-based system that is a real-time health monitoring system utilizing the measured values of body temperature, pulse rate, and oxygen saturation of the patients, which are the most important measurements required for critical care. This system has a liquid crystal display (LCD) that shows the measured temperature, pulse rate, and oxygen saturation level and can be easily synchronized with a mobile application for instant access. The proposed IoT-based method uses an Arduino Uno-based system, and it was tested and verified for five human test subjects. The results obtained from the system were promising: the data acquired from the system are stored very quickly. The results obtained from the system were found to be accurate when compared to other commercially available devices. IoT-based tools may potentially be valuable during the COVID-19 pandemic for saving people’s lives.
