A NEW PATIENT HEALTH MONITORING SYSTEM USING PORTABLE DEVICE

Abstract

This project aims to overcome these limitations by providing a portable, battery-powered, and software- integrated health monitoring system. The proposed system is developed using an ESP32 microcontroller interfaced with four sensors, namely LM35 for body temperature measurement, MAX30100 for monitoring blood oxygen (SpO₂) levels, Heart Rate Pulse Sensor for pulse rate detection, and DHT11 sensor for measuring room temperature. These sensors continuously acquire real-time physiological and environmental data from the patient and transmit it to the processing unit. The ESP32 is configured to create a WIFI hotspot, enabling direct wireless communication between the portable hardware device and a computer system without requiring internet connectivity or cloud storage. A desktop application developed using Python and the KivyMD framework receives the sensor data and displays it on a live dashboard in graphical and tabular formats. The software allows entry of patient details and provides real-time monitoring along with historical data visualization. The system includes automatic data logging, where all sensor readings are stored locally in the computer with timestamp records. The stored data can be exported in PDF and Excel formats, containing both graphical charts and table representations for medical documentation and analysis. Additionally, the system implements a threshold-based warning mechanism that generates alert notifications when abnormal body temperature, pulse rate, or SpO₂ values are detected, ensuring timely observation of patient health conditions. The hardware prototype is powered by rechargeable batteries supported by a battery management system, DC-DC buck converter for voltage regulation, and a DC power jack for charging, making the device fully portable and reliable for continuous monitoring.
