Diseño de un prototipo para el Control de Acceso y Seguridad usando IoT

Abstract

This article presents the prototype design of a system for access control and security using IoT (Internet of Things), taking into account the case study of the Santiago de Cali University laboratory of block 4 floor 3. This design is It consists of a web portal hosted on a web server for administration, two readers, the central and an input module and a web server. The objective was to design a system that allows us to control the entrance and exit of the laboratories through the UUID (universal unique identifier) of the Tag or RFID Card (radio frequency identification), this is consulted from the reader or by the EEPROM memory or in MySQL database. EEPROM memory guarantees the operation of the system, if the reader is not connected to the network to authenticate in the database hosted on the server, the input readers are made with an Arduino card and the central reader with a board Nodemcu; The central reader has nodemcu board and RFID reader, the door reader has an Arduino card, RFID reader, RGB LED, Reset button. The communication of this system is via Wi-Fi, achieving productivity in the execution of the processes. This article will show the operation of the modules connected to the server via Wi-Fi and the input module in the EEPROM, to design the web portal it was necessary to create an Apache server on a Raspberry PI board and, the web portal was programmed with PHP and HTML5, CSS in a Bootstrap 4 Framework to have a Dashboard.
