The project presents a smart refrigerator system that combines camera-based item detection, a touchscreen interface, and a mobile app. It uses AWS cloud services to enable secure data storage, real-time synchronization, and remote user interaction. The system bridges local and mobile platforms for seamless grocery management.
The smart refrigerator system integrates embedded hardware (Jetson Nano) with a cloud-connected Android application to simplify grocery tracking and management. A built-in camera and a Google Net based model are used to automatically recognize items. Users can interact with the system via a local touchscreen or remotely through a mobile app. All data—including shopping lists, in stock, and expired items an expiring soon —is stored in a DynamoDB NoSQL database.
Backend logic is handled by AWS Lambda functions, while user login and authentication are securely managed by AWS Cognito. Sensitive data, such as item quantities, is encrypted using AWS Key Management Service (KMS). The architecture enables real-time, bidirectional syncing between the app and the fridge interface. This solution demonstrates a practical and scalable approach to smart kitchen automation, combining real-time cloud processing with intuitive user interfaces.
