The Smart Health Tracking System is a real-time, wearable IoT-based solution that monitors heart rate, temperature, and SpO2 levels using real-time sensors. Includes fall detection via MPU sensor—ideal for elderly or patient care. Health data is shown on a live dashboard, enabling remote monitoring, early alerts, and smart health management.
It measures:
- ECG (heart activity)
- SpO₂ and Heart Rate
- Body Temperature
- Motion and Fall Detection
- Built using Arduino with embedded C/C++
- Real-time data transmission via Bluetooth
- Displays data on mobile, laptop, or serial plotter
- Triggers alerts on abnormal readings
- Validated through real-patient testing
- Arduino UNO
- AD8232 – ECG sensor
- MAX30100 – Heart Rate & SpO₂
- DS18B20 – Temperature sensor
- MPU6050 – Motion & fall detection
- HC-05 – Wireless communication
| Sensor | Accuracy | Validation |
|---|---|---|
| ECG | ~98% | Compared to clinical ECG monitor |
| SpO₂ & HR | ~97% | Matched standard oximeter |
| Temperature | ±0.2°C | Compared to digital thermometer |
| Motion | ~95% | Fall detection tested manually |
| Wireless | Stable | 10–20m range, ~200ms latency |
This system provides a practical, low-cost alternative to hospital-grade monitors. It is portable, multi-functional, and tested successfully on a real patient — bridging the gap between wearable tech and accessible healthcare.
