Controle do acesso, automatização da climatização e da Iluminação de uma sala de aula, utilizando o Microcomputador de baixo custo RASPBERRY PI.

Abstract

The present work proposes to construct an automated control of a classroom, from the access to the room, to the control of the refrigeration system (air conditioning). Behind the scope of the project came the idea of facilitating the work today carried out by only one employee of the Higher School of Technology (EST), who has the responsibility to open all the rooms in the opening hours of classes, also operating the all air conditioners in the rooms, and, after completion, close all rooms and turn off the equipment. As the "brain" of this whole project, there is the Raspberry Pi microcomputer. It will control access to the room door through a latch by electromagnet which is released by a relay module, will also control the air conditioning through an infrared light emitting module and lights through another relay module. The differential of this circuit is in the data processing. An application built on the iOS platform will store and / or register users who will have access to the rooms in a database contained in a virtual cloud on the application building platform, Firebase. To operate as a drive for the use of peripherals will be used the Arduino electronic prototyping platform. All access to the rooms will be done in two ways: a Radio Frequency Identification (RFID) module and the iOS application. Each employee will have a card or RFID tag registered in their name and also a login to the control application. The function of the application is that, in case of absence of the card, the employee can still gain access to the room and control the systems.
