An IOTML Based Food Freshness Detection System

Numerous food donation applications like ShareThe-Meal [1], Food Need [2], Waste No Food [3], etc., do not specify how food quality can be verified. The quality of food donated could be compromised. This report aims at verifying the quality of food donated to orphanages. The work described in this paper aims to provide authentic information regarding food quality. It also provides a platform to connect catering services and volunteers who carry out the process of food donation to the required beneficiaries. Sensors like MQ2 and MQ135 are used to detect freshness of food. Eclipse IDE, SQLYOG are used to develop the interactive platform. One of the major assumptions made is that the predicted food sensor values are based on samples collected from a few basic food items. It is highly unfeasible to ensure that the classification of food as spoilt or unspoilt is inclusive of all possible food items. This work allows us to assume the categorization of food quality based on only few basic food items. This work aims at a high rate of detection with regard to classification of food as SPOILT or FRESH. The methodology involves the detection of Carbon Monoxide(CO),Ammonia(NH3) and Benzene(C6H6) values in food. The mechanism involved in this work would definitely ensure the quality of food before it is donated to the orphanage.
