Africa Deep Tech Challenge submission: HealthSphere X – AI-powered portable diagnostic tool
# HealthSphere X – AI-powered Portable Diagnostic Tool
*A submission for the Africa Deep Tech Challenge 2025*
---
## 🌍 Purpose
HealthSphere X is a smart, AI-powered health assistant designed for communities with limited access to healthcare. Built around a compact ESP32-based prototype, it helps **predict**, **prevent**, and **prescribe** solutions for temperature-related conditions — even in offline environments.

## ⚙️ Core Features
- 🌡️ Fever & Hypothermia Detection (via MLX90614 sensor)
- 📺 LCD Display for live vitals
- 🚨 Buzzer + LED Alerts for abnormal readings
- 📡 Wi-Fi Sync & Web Alerts via Firebase
- 🤖 AI-based Estimation of Vitals (BP, SPO2, HR)
- 💬 First Aid Bot with Offline Health Advice
- 🛡️ Optional Insurance & Drug APIs for scale
- 🧑⚕️ First Responder Incentive System
---
## 🧠 AI Logic Overview
HealthSphere X includes a lightweight AI simulation model that estimates basic vitals from available data:
- **Inputs:** Body temperature (IR), timestamp, and optional metadata
- **Process:** Regression models trained in Python (scikit-learn)
- **Outputs:** Estimated SPO2, Blood Pressure, Heart Rate
- **Mode:** Deployed offline on ESP32 or simulated via `predict.py`
⚠️ *AI predictions are non-diagnostic and assistive only.*
