Sistema de monitoreo, basado en redes de sensores inalámbricos, para la medición de variables de interés aplicado a la arquitectura bioclimática

Abstract

The objective of this research project is to propose a technological solution for the collection and characterization of environmental variables in enclosures; and with this to be able to contribute with data for the analysis and bioclimatic decision making to be carried out by the experts of the research group GINVEARQUI, of the Faculty of Architecture and the research group UNITEL, of the Faculty of Engineering of Telecommunications of the University Santo Tomas. Specifically, the proposal seeks to implement a wireless sensor network that will allow the monitoring of the environmental variables required in the research (ambient temperature, relative humidity, glass/window temperature, visible radiation, UV radiation, wind direction and speed, and amount of rainfall per unit of time), so that the data can later be compiled, tabulated, and presented in a simple and accurate manner. In the research work developed, we had the opportunity to get to know projects that also had the same technological barrier, where a large number of articles make rigorous studies of environmental conditions and how the variable behavior of the climate affects the different types of existing buildings and for this reason they need to continue to be habitable and be aligned with the requirements of climate comfort and environmentally responsible energy consumption, and how by means of Wireless Sensor Network (WSN) technologies efficient solutions were presented with important advantages such as low energy consumption, local processing, easy deployment, scalability and low cost [1]. In this way, the nodes of these WSNs can carry out the measurement of environmental variables, becoming a great contribution to the different case studies. In order to implement the network, it was necessary to study the different types of communication technologies that could be of greater benefit to meet the development of each of the objectives set, according to this, it was concluded to carry out pilot tests with sensor nodes (called Flocks) of different types of communication, such as GSM and WiFi. Also, depending on the recording environment, have an offline Stand Alone measurement device (with SD memory storage). The selection of the sensors was also made to obtain reliable data that could operate with the selected processing and communication cards. Later, the design of the topology of the network was made and it was connected in a pilot test in the Fray Angelico Building (4 facades and cover), of the University Santo Tomás- Bucaramanga. Finally, the information is displayed on a web platform (for the wirelessly recorded data) and on an online spreadsheet (Google Drive) for information from stand alone devices.
