Redes de sensores sem fio para controle de irrigação

Abstract

The world population growth creates the necessity to expand the agricultural production.This causes an increase in water consumption and wastage in the farming sector,due to inefficient execution of the irrigation. In great part of the rural areas theagriculturist do not have any information about the ground condition of his crops,undermining the decision making during irrigation. A Wireless sensor network for groundhumidity monitoring turns out to be an important resource to the precision agriculture.The information gathered helps reducing the water wastage, increasing the productionefficiency. This final paper has the objective of developing a low cost remote sensingsystem prototype, connected to a base station wirelessly for the irrigation control. Itforesees the implementation of an low energy consumption IPv6 network operating at 915MHz frequency, based on the Contiki operating system, providing the visualization of thisdata via a web interface, using Node-RED system. Relevant tests were performed on thesystem to check the communication reliance and autonomy.
