Food Spoilage Detection Monitoring and Alerting System

Tackling Food safety measures and mitigating spoilage are critical Challenges in public health. In the present work, robust solution for the continuous monitoring and management of perishable food products is observed. By incorporating temperature and gas sensors, Food Spoilage Detection and Alerting System using IoT is designed to detect early signs of spoilage, enabling timely intervention to prevent food waste and its safety. The temperature sensor monitors the surrounding environment, emphasizing the crucial role of temperature in accelerating the spoilage of sensitive foods such as dairy and meat. In tandem the gas sensor detects specific volatile compounds such as Ethylene, Ammonia, Methane, Nitrogen Dioxide, and Carbon Dioxide that act as indicators of food degradation, allowing for the identification of spoilage risks before they become significant. NODEMCU microcontroller is central to the system's operation which is an efficient and compact IoT platform that gathers and processes data from the sensors. It uses predefined thresholds to evaluate environmental conditions, ensuring accurate spoilage detection. Real-time data is displayed on an LCD screen, giving users immediate access to food storage conditions. If gas levels exceed the predefined thresholds, the system triggers an alert message, notifying users of potential spoilage. Alerts are generated through the UBIDOTS app and delivered via email or registered mobile number, providing timely notifications that enable users to take prompt action in maintaining food quality.
