Food Quality Monitoring System Using IoT

Abstract

In recent year’s food wastage has become major problem due to contamination. This is mainly due to the process of storage methods and lack of knowledge on a biotic environmental factors such as temperature, humidity and sunlight. Hence it is necessary for one to maintain food quality throughout the food supply chain. Effective food quality maintaining mechanisms are essential to safeguard the food quality. Therefore, we have interfaced different sensors to monitor the food products. These innovations have led to improved food quality, usability and food safety. The environmental factors can be monitored by DHT11 sensor and MQ3 sensor that are interfaced with Arduino UNO. In this project the real-time data of environmental factors is collected through cloud and are monitored. If the monitored value of any of the factors crosses the threshold value then the person monitoring will be notified via sms through SMTP gateway service and he can them through the mobile application.
