Design and Implementation of Smart Refrigeration System using IoT Devices

Home appliances have eased the day-to-day requirements of storing vegetable and fruits for longer time in the kitchen. A refrigerator has become an integral part of the home setup. The refrigerators come in different configurations and make. The existing refrigerators comprises of single tire architecture. It requires considerable efforts in hardware installations for intelligent control and monitoring leading to higher costs. In this paper we propose the design of a smart refrigerator using the IoT devices to communicate efficiently between the hardware and the user. It uses ARM processors and sensors for acquisition of system parameters and processing them to initiate appropriate operation or to signal messages. Our approach implements the smart refrigerator using a standard setup configuration and generates alerts based on parametric evaluation against the current state of the system. The refrigerator can effectively address the issues in quantity monitoring, quality monitoring, perishable items and the quality of shelf life in event of expiry of the packaged goods. The results are encouraging when the refrigerator was put to operation.
