Projeto e implementação de transdutores para um sistema de monitoramento agrometeorológico

Abstract

Modernization of agriculture is a growing branch of technology. The environmental conditions directly influence the growth and production of a plantation, knowing the variables of temperature, humidity, rainfall and solar irradiation can help in decision making: when planting, fertilizing, harvesting and others. This work presents the project of an Agrometeorological Station, to perform the monitoring of the conditions in an agricultural environment, with the humidity sensors of air and soil, air and soil temperature, temperature and voltage of the battery, and air velocity. The circuits were tested in protoboard and developed in circuit board. The data is displayed on an LCD display and saved on an SD card via the shield logger. The microcontroller board used was the Aduino UNO and the code was developed in its own programming language. For the protection of the sensors, board and battery, the physical part of the station was built. The project monitored the sensors for a few hours, in which it was then possible to plot the graphs with the measured variations, and to perform some analysis on the results obtained. It was noted to be a feasible and implementable project, requiring some improvements in the manufacturing of the board and alteration of the sensors used.
