Deployment of IoT for smart home application and embedded real-time control system

Abstract Expeditious enhancements in technology and consumer electronics push towards the unavoidable usage of intelligent devices in everyday life. These smart devices play a vital role in enhancing human comfort and ensures better standard of living. The refrigerator is one of primary appliance that is utilized in everyday life where many food items and grocery things are placed. The items that are placed inside the refrigerator need to be monitored for better utilization and also to avoid the wastage. This work aims to convert the traditional refrigerators to smart refrigerator that detects the shortage or spoilage of items using the item information from the database created. The proposed system automatically control the refrigerator temperature according to varying conditions using thermostat control and provides the motorized control of the door for energy saving and efficient cooling. The system also provide motorized control of the door for energy saving and efficient cooling. This internet of things (IoT) based system allows to monitor the food items that are placed inside the refrigerator and utilization of other grocery items before the expiry date. In addition to, this works also aims to place the online order of expired items by providing the app notification and also sends a short message service (SMS) text message to the user smart phone. We have identified and loaded the items available online search engines in our database. Based on the user input, this system will identify the link with less cost and expected delivery time of the needed items, therefore the user can select ordering of items accordingly. The characteristics of utilized components and materials are presented.
