Abstract

Health Monitoring System is an IoT-based solution designed to continuously monitor a patient’s vital health parameters in real time. The system uses wearable sensors to measure body temperature, heart rate, blood oxygen level (SpO₂), ECG, and other critical signs. The collected data is transmitted to a cloud platform or mobile application, allowing doctors and caregivers to monitor patients remotely.

This system is especially useful for elderly care, chronic disease management, post-surgery monitoring, and emergency detection. By enabling real-time alerts and data tracking, it improves healthcare accessibility, reduces hospital visits, and ensures timely medical intervention.

Existing System

1. Manual health checkups at hospitals
2. Periodic monitoring instead of continuous tracking
3. Paper-based medical records
4. Delayed emergency response

Limitations:

1. No real-time monitoring
2. Requires frequent hospital visits
3. High healthcare costs
4. Delayed detection of critical conditions

Proposed System

1. Wearable sensors for real-time vital sign monitoring
2. IoT-enabled device for continuous data transmission
3. Cloud-based storage and analytics
4. Mobile/Web dashboard for doctors and caregivers
5. Emergency alert system (SMS/Notification)
6. Historical health data tracking and reporting

Software Requirements

1. Programming Language: Python / Embedded C
2. Arduino IDE / Raspberry Pi OS
3. Database: MySQL / Firebase
4. Web Framework: Django / Flask
5. Mobile App: Android Studio / Flutter
