Resumo
O mundo está em constante evolução e passando por uma revolução tecnológica. Tarefas onde antes era preciso estar no local para executar, hoje podem ser realizadas remotamente ou ainda podem ser automatizadas com o uso de sensores e dispositivos inteligentes, proporcionando conforto, economia e segurança. Utilizando conceitos e conhecimentos de hardware e software obtidos ao longo do curso de Engenharia da Computação, este trabalho apresenta o desenvolvimento de um sistema domótico, responsável pelo gerenciamento e monitoramento de dispositivos elétricos conectados à uma rede sem fio. Foram utilizados dispositivos da marca Sonoff como atuadores do sistema, módulo ESP8266 NodeMCU ESP-12E para realizar a leitura de temperatura e umidade do sensor DHT22 e um mini-PC Raspberry Pi 3 como servidor da aplicação. O meio de comunicação principal dos dispositivos é a conexão Wi-Fi pela qual é possível controlar a iluminação, além de outros dispositivos do local automatizado. Foram realizados testes de acionamento dos dispositivos de forma manual, pela aplicação e via agendamento de tarefas onde em ambos os casos o sistema registrou os dados, comportando-se da forma esperada. Após os testes, foram analisados os resultados e constatado a economia de energia que um dispositivo pode apresentar mediante o agendamento de tarefas com desligamento automático. O hardware escolhido, bem como a aplicação desenvolvida atingiram de forma satisfatória o objetivo proposto, proporcionando praticidade e conforto através da aplicação, além de economia de energia resultante do gerenciamento agendado.

Were used devices of the brand Sonoff as system actuators, ESP8266 NodeMCU ESP-12E module to accomplish the read of temperature and humidity of the sensor DHT22 e a Raspberry Pi 3 board as the application server. The main means of communication is the Wi-Fi connection through which it is possible to control the illumination, in addition to other devices in the automated place. Device activation tests were performed manually, through the application and via task scheduling, where in both cases the system recorded the data, behaving as expected. After the tests, the results were analyzed and the energy savings that a device can present by scheduling tasks with automatic shutdown were verified. The chosen hardware, as well as the developed application, satisfactorily achieved the proposed objective, providing practicality and comfort through the application, in addition to energy savings resulting from the scheduled management.
