A system for home and grocery refrigerators has been developed and proposed for an intelligent refrigerator, although it has not yet been implemented. An intelligent refrigerator system's basic architectural and electrical design as well as its software simulation, operation, and analysis as well as its hardware implementation are shown in this prototype. In order to collect data on the physical environment and properties of the system both inside (within the fridge) and outside, several sensors including weight sensors, pH sensors, contact sensors, and temperature sensors have been used in this system (compressor unit). The fridge keeps track of stock levels and freshness levels by analysing that data. For remote control, stock and freshness information, and alarming of any hazard (overheating compressor unit, open door etc.), the proposed Intelligent Refrigerator control unit includes numerous sensors and arrays. You can utilize an LCD screen to show notifications and alarms. An optional IP camera has been installed inside the fridge for continuous monitoring. For the benefit of users, an android app has been created (owner, store manager etc). For command and notification reasons, Bengali language voice recognition has been incorporated into the system. Additionally, an Android software has been developed that uses the mobile phone's GPS technology to locate nearby supermarket and superstores (such as Kacha Bazar, Aagora, and Swapno).
