Разработка умного холодильника без продавца

Abstract

Today's technological progress has allowed the use of intelligent devices and machines al-most everywhere. The refrigerator is considered one of the most important appliances, which is used almost everywhere for the purpose of storing food, beverages, and medicines at low temperatures and in a closed  place to avoid exposure. There is such a problem as the lack of cashless vending machines, the unavailability of information about the location of vending machines, etc. As a solution to the above problems, a smart re-frigerator is offered. The proposed smart refrigerator uses a Radio Frequency Identification (RFID) reader, an Arduino Uno microcontroller, RFID tags for all items in the refrigerator, a user-friendly application de-veloped using Microsoft Visual Studio, Python, a core MySQL database developed by vendors to store in-formation related to each purchased item, and a GSM/GPS A7 module, with support for GPRS data trans-mission.
