Introduction

I. INTRODUCTION

The growth of healthcare is accompanied by rapid technological advancements, particularly in the wake of the recent Coronavirus outbreak that negatively impacts China's economy. Technology that monitors remote health offers a promising solution for managing patients during epidemics. IoT-based health monitoring systems offer cutting-edge solutions in this regard. [1].

The Internet of Things (IoT) is a huge network of networked objects that exchange data easily because of its embedded electronics, sensors, software, and connectivity. People, machines, and the environment can all communicate remotely with one another at any time and from any location because to this complex network of gadgets. IoT is essential to patient monitoring in the healthcare industry since it enables medical professionals to monitor patient health data remotely and take immediate action. Remote Patient Monitoring enabling patients to receive care from the comfort of their homes which   extends beyond the confines of traditional clinical settings. This innovative approach expands access to medical services while simultaneously reducing accessory costs [2].

The central goal of this project is to create and implement a smart patient health monitoring system that utilizes sensors which includes Heartbeat sensor, temperature sensor, ECG sensor to gather patient health data and employs the internet to notify their family members in case of any anomalies. This system aims to minimize the need for in-person physician visits (such as doctor, nurse), hospital stays, and diagnostic testing procedures. [3]

Human bodies generate valuable health data, including pulse rate, body temperature. This data can be continuously monitored using sensors which collects data from patient connected to a microcontroller. The microcontroller (ATmega328P, RP2040 chip) processes the data and displays it on an LCD screen. Additionally, the system can send alerts to

remote users via the internet if any sudden changes in vital signs are detected. This IoT-based patient monitoring system allows for real-time tracking of health status and timely intervention when necessary, potentially reducing the need for in-person doctor visits and hospital stays [4].

In remote areas, where medical facilities are often unable to be reached, people often ignore minor health issues, such as dysregulation in body temperature and heart rate, until they become lethal or life threatening. This can lead to unnecessary medical expenses and even several consequences. To cover this issue, providing remote patient monitoring systems, equipped with smart sensors, could be a cost-effective and life-saving solution [5][6].

The development in field  of IoT-based HMS has empowered common people to access important physiological data from the comfort of their homes. This integration of healthcare with IoT has revolutionized for elderly patients, eliminating the need for involving and exhausting trips to the hospital. Our proposed study installs a selection of specialized bio sensors to monitor vital parameters such as heart rate, oxygen saturation levels, and body temperature.[7]

II. LITERATURE REVIEW

A. Introduction

A health monitoring system was implemented and designed to monitor basic patient symptoms, including body temperature, oxygen saturation (SpO2), heart rate, and eye movement, using an IoT Sensor. The system employed Heartbeat, SpO2, Temperature, and Eye blink sensors for data acquisition and Raspberry Pi or Arduino-UNO board for processing. While the system was successfully implemented, no specific performance metrics regarding patient monitoring we provided [8].

Presented a healthcare monitoring kit using the Internet of Things (IoT) interface. The method effectively takes record of fundamental health parameters, such as respiration, heartbeat, body temperature, and ECG. The primary hardware components employed were a pulse sensor, temperature sensor, BP sensor, ECG sensor, and microprocessor Raspberry Pi. Sensor collects data from patient and transmitted to the Raspberry Pi for processing, followed by further transmission to the IoT network and cloud. The system's primary drawback was the absence of data reading and data visualization section [9].

Suggested an easy approach for detecting pulse rates in a system. The suggested system was a real-time monitoring tool since it employed the plethysmography procedure and digitally showed the results. When compared to other intrusive treatments, the patient has found the method to be dependable. [10].

In this proposed system, a heart rate monitoring device that runs on a smartphone. The device tracked finger blood flow using a mobile light and camera, calculating cardiac output based on blood flow. The devised technology allowed users to

check their heart rate without constantly moving their hands

by describing an integrated gadget that wirelessly sent a person's pulse to a computer. Although this idea is great, it cannot be implemented if continuous cardiac monitoring is required [11].

They created an IoT safety monitoring gadget that is adaptable. Three levels comprise the framework configuration: the control layer, the device layer, and the transport layer. In the control section, a DS18B20 sensor was utilized to monitor body temperature, and a pulse sensor was employed to measure pulse. On the transport layer, the Ethernet shield and Wi-Fi module allowed the data to be loaded from Arduino into the cloud. The server information was ultimately gathered by the framework layer. Unfortunately, since an Arduino Uno was utilized in this instance, many sensors cannot be handled correctly. [12]
