Herramienta de adquisición de datos en un vehículo aéreo no tripulado para detección de variables climatológicas en un invernadero.

Abstract

The next document describes the development of a tool which is used to get information from a greenhouse, this was put in an unmanned aerial vehicle in order to measure different climatic variables. This tool is divided in 4 parts: first, the Unmanned Aerial Vehicle (UAV), the monitoring system, the control system and the user interface. The first is a Quadcopter SK45 Turnigy with an air controller kk2.1.5 and it has 4 motors without brushes Brushless Multistar 2214 935kv and a maximum thrust of 850 g for every engine, this detail is necessary to get a functioning correct of the system due to the weight of the UAV. Second, The monitoring system is used to do an approximation of the climate conditions in the greenhouse and it has 4 sensors: light sensor (TSL2561), air quality sensor (MQ-135), temperature sensor (DHT11), relative humidity sensor (DHT11) and in addition to that, it was added an ultrasonic sensor HC-SR04 to get information in relation to the elevation of the vehicle and this variable is taken into account to do a graphic about the different physical variables that can be measured. Third, the programming system is put in the PsoC 5 LP CY8CKIT-059 microcontroller and it has a CY8C5888LTI-LP097 with which the programming and recording of the monitoring system and every sensor and in this way, to send information through the modules of the communication Xbee serie 2 and it used a communication protocol Zigbee. Fourth, finally, the user interface was made using LabView software, where it is possible to see every climatic variables which was measured for further analysis.
