Smart Public Health Monitoring System

Elevator Pitch

A low-cost IoT-powered health monitoring solution that uses wearable sensors and cloud dashboards to detect abnormal vital signs in real time, enabling faster interventions and proactive healthcare during public health crises.

Inspiration

The COVID-19 pandemic and other health crises revealed the need for fast, scalable public health monitoring. Manual checks are time-consuming and resource-intensive. We wanted to create a system that leverages IoT to automate real-time health data collection, enabling early detection and faster responses.

What it does

Continuously monitors heart rate, body temperature, and oxygen levels
Sends data to a cloud platform for real-time analysis
Displays results on a user-friendly dashboard
Generates automatic alerts to healthcare workers when abnormal readings are detected

How we built it

Hardware: Arduino + biomedical sensors
Connectivity: ESP32 modules with Wi-Fi + MQTT protocol
Cloud: Central server for data storage & analysis
Dashboard: Web-based interface for visualization
Alerts: SMS/app notifications when thresholds are crossed

Challenges we ran into

Maintaining sensor accuracy to avoid false alarms
Handling network instability with retry mechanisms
Ensuring data security with encryption and secure channels

Accomplishments that we're proud of

Fully functional end-to-end prototype integrating hardware, cloud, and frontend
Live dashboard with real-time visualization
Reliable alert system for urgent health events
Feasible scalability at a low cost
