RESUMO

It is increasingly necessary to optimize the agricultural production due to environmental or economic pressures imposed by global markets. Aiming at increasing the efficiency of agricultural production come the need to exert greater control in the procedures adopted, especially in poultry barns. The development of control and monitoring systems based on Wireless Sensors Network Sensors (WSN) is an alternative form of communication for barns, due to the mobile characteristics of these networks. The development of the monitoring system for poultry production based on WSN performed on this work sought to establish a compromise relationship among the demands of national applications, compatibility with the existing international standardizations and affordable prices to the Brazilian agricultural sector. Methodologically, was made a radiofrequency site survey in a poultry barn, as well as channels allocation planning. The wireless technology used was Zigbee, with standard IEEE 802.15.4 setting up the physical layer and link layer. To automate the powers measurement a Delphi language software was developed and, for the site survey, was used an adjusted model of the Shadowing. All tests were performed in the Moretto s poultry Barn, in the city of Tuiuti, state of Sao Paulo, Brazil. The results of this study indicate that Zigbee technology is appropriate, from the perspective of signals propagation, to implement WSN in poultry barn
