IoT-Sensor Integrated Smart Food Freshness Scoring System

Monitoring food and detecting its freshness is crucial for ensuring food safety, reducing waste, and optimizing supply chains. Traditional methods rely on retroactive expiration dates, and recent models do not consider real-time temperature fluctuations, leading to inaccurate shelf-life estimation and unnecessary waste. This article presents an innovative framework for food monitoring and freshness scoring systems integrating the IoT and sensors. A unique freshness scoring model is developed to calculate the freshness score in numerical value and categorize the current state of the food into different classes based on its temperature. In addition, sensors and IoT devices are utilized to collect and analyze food temperature data. As IoT and sensors are integrated, this proposed system can continuously monitor temperature and calculate the freshness score at any stage of the supply chain. The result analysis shows that the IoT device can continuously collect the real-time temperature of food using the sensor. Then, the proposed system can effectively calculate the innovative freshness score using the proposed model. This proposed system can help businesses and consumers make informed decisions by providing real-time freshness insights and calculating the freshness score, ultimately improving safety and sustainability.
