🌐 Backend APIs

The backend is built using Node.js with Express.js, handling:

• Sensor Data Processing

  • REST endpoints for receiving sensor data
  • WebSocket support for real-time updates
  • Data validation and sanitization

• Machine Learning Integration

  • Python child processes for ML model execution
  • API endpoints for fertilizer recommendations
  • Crop-specific prediction models

• Weather Data Integration

  • Weather API proxy endpoints
  • Forecast data caching
  • Weather alert system

• Device Control

  • IoT device management endpoints
  • Motor control API
  • Irrigation scheduling system

• Authentication & Security

  • JWT authentication
  • Role-based access control
  • API rate limiting

🛠 Setup

git clone https://github.com/IMMANUEL-88/ferti_optimizer.git
cd ferti_optimizer
flutter pub get
flutter run

Note: While you can clone and run the app locally, please be aware that:

• Some backend APIs are currently hosted on a local server (localhost), and others are hosted live.
• To experience full functionality (ML predictions, sensor data sync, motor control, etc.), you’ll need to set up the backend environment locally or deploy it to a live server.
• The necessary environment variables (.env) are maintained privately and are not included in the repository for security reasons.
