IoT in Healthcare: Enhancing Remote Patient Monitoring

As technology progresses and sensors diminish in size, there is a desire to incorporate them into a wide range of sectors to improve human life. Technology integration in healthcare is an important research area. Healthcare is not always affordable, especially in poorer countries. This program aims to address a contemporary healthcare issue in society. In recent years, IoT has gained popularity in a variety of industrial industries, most notably automation and control. This project utilizes IoT technology to enhance remote patient monitoring by giving real-time data on important health signs namely blood oxygen levels (SpO2), temperature, and heart rate. The system's primary controller is an Arduino, which is connected to an ESP8266 module for wireless communication and a SPO2 sensor for health data collecting. The data is displayed locally on an LCD screen, and any abnormal results are alerted by a buzzer. The MQTT protocol facilitates seamless data transmission to an IoT-based panel application, enabling healthcare professionals and caregivers to remotely track patient health. Design and deploy an Internet of Things (IoT) system that continuously records vital signs and delivers real-time alerts to medical experts, enhancing patient care—particularly for individuals in remote locations or home-based settings.
