Pi-Sync 🏢🔐

Pi-Sync is a thesis project designed to revolutionize access control in condominiums by integrating modern technologies with centralized management. The system features a Django Rest Framework API as the central brain, syncing mobile and desktop platforms with Raspberry Pi devices for seamless door management and access tracking.

Features ✨

Centralized Dashboard 🖥️

• Built with C# WinForms, running on the desktop for admin users.
• Manage users and rooms with full CRUD functionality.
• Log all door access activities for monitoring and security.

Tenant Mobile App 📱

• Mobile App: Developed with Kotlin and Jetpack Compose Material 3 for Android tenants.
• Provides tenants with door access controls and status.

Access Methods 🔑

1. Physical Key: Used only as a backup when the system is not functioning, acknowledging that no system is perfect.
2. Fingerprint Recognition: Authenticate users with stored biometric data.
3. Mobile Control: Unlock doors via the mobile app over the network.

Synchronization 🔄

• Real-time syncing of access data and logs between the mobile app, desktop admin dashboard, and Raspberry Pi devices.

Activity Logging 📝

• Tracks and records door access events, providing a complete audit trail.

System Architecture 🏗️

• The Django Rest Framework API serves as the central brain 🧠, managing data, authentication, and synchronization across platforms.
• The Raspberry Pi 5 acts as a hardware controller 🖲️, directly managing door components like solenoids and fingerprint sensors.
