Estudo e implementação do protocolo de comunicação MQTT aplicado a um sistema de automação predial.

Abstract

The number of smart devices with capacity of monitoring, processing and communication has increased significantly during the past years. In this scenario the Internet of Things (IoT) comes to enable these objects to be connected to the Internet and promote communication between users and devices. However, several practical and social challenges emerges. For instance, it is necessary an efficient way for exchanging data between these billions of devices once these objects, in its majority, have resources such as memory and processing very limited. The present work proposed, in a first moment, make an study of the MQTT communication protocol. Due to its simplicity and efficiency, this protocol represents a great alternative for IoT projects. Following, as a proof of concept of the protocol, it was developed an automation system for monitoring the temperature, humidity and luminosity of a room and control the air conditioner and some lamps inside the room by using the MQTT protocol.
