Sensors, GPS, and Immutable Ledger for Enhancing Transparency and Traceability in Food Supply Chain

Food safety together with quality control and consumer trust can only be achieved through transparent and traceable food supply chains. This research presents an integrated framework which employs IoT sensors alongside GPS tracking alongside blockchain technology to create improved visibility and security throughout the food supply chain. The integration of IoT devices enables blockchain-based storage of immutable temperature and humidity and location data while smart contracts perform automatic compliance verification processes. Consumers gain access to product documentation through quick response codes for better product trust and liability tracking. The system strengthens operational efficiency while decreasing food waste and resolves common supply chain problems including fraud and operational inefficiencies and transparency issues. There are substantial advantages in the framework yet scalability difficulties together with regulatory obstacles and implementation expenses continue as operational hurdles. Future studies will examine the application of artificial intelligence analytics and improved security measures as well as sustainable blockchain models to improve system efficiency. The research establishes a building block to merge emerging tech solutions into food value chains which secures safe operations while making systems more visible and boosting industry efficiency across all food production sectors worldwide.
