Diseño e implementación de una red con sensores inalámbricos (wsn) con un protocolo abierto de comunicación basado en IEEE 802.15.4 (XBEE) para prácticas universitarias.

Abstract

The use of sensory devices has been increasing over time and expanding its operational field, taking place, not only in processes of industrial areas, but also, in less extensive areas where the control of environmental factors is required. Through an exhaustive study of the different theoretical and practical contributions, certain concerns arose regarding a research problem about the implementation of intelligent wireless sensor networks, for different environments, and were developed in an efficient way, through a programming that allowed the use of devices electronic devices, which in turn were communicated through an open protocol based on the 802.15.4 standard. (XBEE) The network that was implemented is composed of four sensor nodes, consisting of a base that contains: an Arduino electronic board, an XBee electronic device and sensory devices such as humidity and temperature, which are connected to a ring topology, this type of topology will help us easily and quickly transmit and receive data from each of the nodes connected to said network; the XBee modules are configured through the XCTU program, with an ID which will allow us to connect to this network wirelessly and thus process the data received wirelessly in order to store it in a database for later analysis. Ten practices were elaborated with their corresponding steps and indications, from how to connect and configure an XBee device to the transmission of data with their respective graphs in Matlab, which gives us a great advantage of avoiding the excessive amount of wiring; prior to the construction of the network, the conceptual study was carried out focused on the different elements that make up the network, types of topology to be used, software, communication protocols and applications.
