Diseño de un prototipo electrónico de peso ligero para prospección eólica preliminar con un globo cautivo.

This research aims to design a lightweight electronic prototype for a preliminary wind survey with a captive balloon, which allows the interpretation of speed profiles. For the design of the prototype, the characteristics of the wind, the selection of sensors for speed, direction, temperature, relative humidity, height above sea level, and atmospheric pressure were considered. One feature that this project presents is data storage on a removable device. Its construction in PLA (polylactic acid) material, melted at 190 ° C in a 3D printer, for the design of a frame that carries the electronic board, by lifting the device from the earth's surface with a meteorological balloon filled with 3m³ of helium gas which lifts a maximum force of 49 [N]. A wireless transmission will be used to verify the variables of the wind potential and an I2C communication to decrease the required ports in the microcontroller, an RS232 connection to measure the wind speed utilizing a direct current motor. The computational mechanical and electronic design tools allow simulation using software to analyze the behavior of each of the devices, through a master-slave network that enables the interpretation of wind survey with statistical tables to be interpreted with software, which will be represented with a compass rose that indicates the predominant wind speed and direction from the south to the east, with a recorded frequency of 0.5 to 2.10 m / s and a total measurement error percentage of 10.30% in the results obtained due to the height difference between the prototype and the meteorological station.
