Diseño e implementación de un drone autónomo para el monitoreo de una red WSN de sensores meteorológicos utilizando dispositivos XBee para transmisión de datos en la ESPOCH.

Abstract

It was developed a prototype of a wireless sensor network (WSN) which will be monitored by a drone responsible for taking data from ambient temperature in the ESPOCH, the system provides the benefit of being easy to handle and has low cost. Due to the agility that the drone have to fly it is possible to supervise in a short time large areas. The system was structure as a network type star, being furthermore unidirectional by the requirements outlined; it offers the option of adding new routers if necessary. It has a coordinating node and two nodes routers, totally independent, they are based on the free Arduino hardware platform, and they are responsible for data collection and transmission of information to the coordinating node, this one in turn consists of a secure digital micro card (SD) which stores in a file the compiled information. The communication between nodes is conducted with wireless communication devices (Xbee S2) with a range of 37 meters of radio when fed with 3.3 volts. From the test carried out in the investigation it was confirmed that the system when acquiring the date of the ambient temperature present an error of ± 1 ° C, it also presented a stability of 98.35% within the information transmission in the nodes routers and the efficiency ratio presented by the system is 180%. It was concluded that the wireless sensor network provides information that helps to generate historical databases, allow to supervise areas of difficult access without endangering people at the time of this work. The installation of a renewable energy system for the indefinite autonomy of the system.
