Ensuring the freshness of food products is essential for both acute and chronic health outcomes. However, significant health risks can be triggered by dietary resources subjected to improper storage protocols. Current methods are often unreliable and infeasible for detecting food freshness. This research proposes an IoT-based food freshness detection system that integrates a suite of electrochemical and gas sensors-including pH, moisture, and ethanol sensors-to assess food freshness and reduce health risks associated with spoilage in perishable items like meat, produce, and dairy. The system is integrated with a mobile application that allows users to analyze food quality in real-time, bas... More >
