O objetivo deste trabalho foi projetar uma rede de sensores sem fios para a monitorização de diversas variáveis de interesse numa habitação, relacionadas com a qualidade do ar interior e com o consumo elétrico.
Inicialmente foi feita uma pesquisa sobre os parâmetros relevantes a serem medidos numa habitação e, posteriormente, pesquisaram-se produtos e trabalhos desenvolvidos com o mesmo intuito. Com base nas informações encontradas, os parâmetros selecionados foram a temperatura, a humidade, o dióxido de carbono, os compostos orgânicos voláteis, as partículas em suspensão e a corrente elétrica.
Projetou-se a rede de sensores sem fios, recorrendo a três tipos de nós, o nó terminal, o nó router e o nó coordenador. Foram desenvolvidos cinco protótipos, para medição dos parâmetros, e um outro, ligado ao coordenador, para a receção e armazenamento dos dados. Este módulo também permitiu visualizar os dados em tempo real através de uma aplicação web.
Com estas medições pretendeu-se, através de um sistema económico, relativamente pequeno e de baixo consumo, que o utilizador tenha uma melhor perceção da qualidade do ar interior e do consumo de energia, e que possa adotar medidas para melhoria do conforto interior e para o controlo da energia consumida.
The objective of this work was to design a wireless sensor network for the monitoring of several variables of interest in a house, related to indoor air quality and electricity consumption. Initially research was done on the relevant parameters to be measured in a house and was done on products and projects developed with the same intention. Based on the information found, the parameters selected were temperature, humidity, carbon dioxide, volatile organic compounds, suspended particles and electric current. The wireless sensor network was designed using three types of nodes, the terminal node, the router node, and the coordinating node. Five prototypes were developed to measure the parameters and the coordinator was developed for data reception and storage. This module also allows you to view the data in real time, through a web application accessible in the local network. With these measurements and their results, a relatively small and low-energy system is intended to provide the user with a better perception of indoor air quality and energy consumption, empowering the user with knowledge to improve those parameters.
