Projeto ubique: rede de sensores sem fios para edificações inteligentes

Abstract

Commercial and residential buildings are becoming more modern and efficient as a consequence of the use of smart technologies. At the same time, the decrease of production costs and miniaturization of new technologies allowed the rise of a new device group called smart objects that together make the Internet of Things. This area has grown in the last years, accelerating and spreading the usage of technologies in smart buildings. In this context, this work presents the development of a wireless sensor network called Ubique Project that aims to provide buildings with intelligence. The Centro de Informática at Universidade Federal da Paraíba was used as a case study. A complete access control system (hardware and software) was developed to validate the wireless sensor network. The hardware was based on Espressif ESP8266EX microcontroller and 13.56 MHz RFID technology. The software was developed with the aid of Arduino (embedded system) and Laravel (web server) frameworks. Some security issues were raised, but they were not addressed in this work because they are inherent to the Internet of Things area and are still being evaluated. The development of this project allowed the validation of knowledge acquired during all Computer Engineering course, specially in areas such as Software Engineering, Embedded Systems and Wireless Sensor Networks.
