RESUMO

The development of systems able to join different technological tools is very important in order to provide support for Precision Agriculture and it stimulates the creation of interdisciplinary teams to obtain favorable results to increase agricultural productivity. The main goal of this work is to study applications of embedded sensing systems in agricultural machines, exploring the interface between computer science, mechanical, electrical, and agricultural engineering using concepts and technologies of measurement systems. It was developed two on board sensing systems. The first system collected the data of crop reflectance and plant height in sugar cane growing area. The second one controlled the variable rate fertilizer distribution based on reflectance of maize crop. Were used the sensors Crop Circle (reflectance to monitor the status of the plant), Sonar (plant height) and GPS (Global Positioning System), which were applied to detect some possible error sources during field operation. The systems developed fulfilled the role of integrating knowledge, providing practical observations about the needs, failures and successes in developing embedded systems for use in agricultural production
