Desenvolvimento de um sistema de baixo custo baseado na tecnologia RFID para gestão de estoque

Abstract

This paper shows some difficulties seen in inventory management at Energisa Mato Grosso's Substation and Line Maintenance Department (DMSL) in the city of Cuiabá. A solution founded through the installation of an inventory control system based on RFID technology is also presented. The document provides a brief contextualization of the theory and practice of inventory, its concepts and its history; it is also discussed, in more depth, about RFID technology, its history in the world and in Brazil, its applications and comparisons with other recognition technologies. After that, a bit of the reality and history of Energisa and the stock in the DMSL are shown. Next, the motivation for the project is presented, as well as the development and results obtained with the application of this system. Behind this, the functioning of components used for the construction and testing of models is also studied until the definitive model is obtained. Are seen: the MFRC522 module (RFID), the Arduino UNO microcontroller, the ESP-32 microcontroller and the ESP 8266 module (WiFi). The integration of the same to the database in the Excel program is seen, and the benefits and/or difficulties with each one of them are presented. At the end of the document, the results and discussion of the project are shown.
