ProtectMe - Personal Safety App

Overview

ProtectMe is a personal safety and medical emergency application designed to ensure the safety and well-being of users. The app integrates IoT (Internet of Things) technology with a mobile application to provide real-time location tracking, emergency alerts, and heart rate monitoring. It is developed for both Android and iOS platforms using Flutter and Dart, with backend services powered by Firebase.

The app allows users to:

• Send emergency alerts to predefined contacts with their real-time location.
• Monitor heart rate using IoT sensors.
• Locate nearby emergency services such as hospitals, police stations, pharmacies, and medical clinics.
• Provide detailed directions and transportation options to reach these services.

Features

For the Primary User:

1. Emergency Alert: Send instant alerts to predefined contacts with the user's real-time location.
2. Heart Rate Monitoring: Continuously monitor the user's heart rate using IoT sensors.
3. Nearby Services: Locate nearby hospitals, police stations, pharmacies, and medical clinics.
4. Real-Time Location Tracking: Share the user's real-time location with emergency contacts.
5. Contact Management: Add, edit, or remove emergency contacts.
6. Profile Management: Update personal information and view health metrics (e.g., heart rate, steps).

For Emergency Contacts:

1. Real-Time Location Tracking: View the primary user's real-time location on a map.
2. Emergency Notifications: Receive instant alerts when the primary user triggers an emergency.
3. Contact Management: View and manage the list of users who have added them as emergency contacts.

Technologies Used

Frontend:

• Flutter: For cross-platform mobile app development.
• Dart: The programming language used for Flutter.

Backend:

• Firebase: For user authentication, real-time database, and cloud storage.
• Firestore: NoSQL database for real-time data synchronization.
• Foursquare API: For locating nearby emergency services (hospitals, police stations, etc.).
• Google Maps API: For real-time location tracking and directions.

IoT Components:

• Arduino UNO: For heart rate monitoring and data collection.
• Raspberry Pi 4: For GPS tracking and emergency alert triggering.
• GPS Module: For real-time location tracking.
• Heart Rate Sensor: For continuous heart rate monitoring.
• LCD Display: For displaying heart rate data.

Programming Languages:

• Java: For Android app development.
• Python: For IoT device programming (GPS and button press).
• C++: For Arduino programming (heart rate sensor).

Architecture

The app follows the MVC (Model-View-Controller) architecture:

1. Model: Handles data and business logic (e.g., user data, heart rate, location).
2. View: Manages the user interface (UI) and displays data to the user.
3. Controller: Acts as an intermediary between the Model and View, processing user interactions and updating the UI.

Physical Architecture:

• IoT Devices: Arduino and Raspberry Pi for heart rate monitoring and GPS tracking.
• Mobile App: Flutter-based app for user interaction and data visualization.
• Backend: Firebase for real-time data storage and synchronization.
