Rede de sensores sem fio para aquisição e controle de variáveis ambientais em instalações industriais para frangos.

Abstract

Through the use of automated systems for environmental control, the environmental variables of the poultry houses can be kept within the limits where the species can express their great genetic and productivity potential. For the control of a variable it is necessary to measure this variable, compare it with a reference value and trigger the system that can influence it. The system is designed to acquire data on environmental variables and has the ability to control the main equipments used to improve the internal environment of the poultry house. The most important environmental variables were considered - temperature, relative humidity and light - although the system can measure other quantities. The control will be done to keep the internal environment of the housing within the range of thermal comfort for the species. The system operates as a wireless network of sensors and actuators and can be suitable for various types of sensors and actuators, simply adding modules and changing their programming. Although developed for the production of broilers due to its economic importance, the system can be applied to other animal species. The tests showed good results in the laboratory. Given the proposed objective, the system measures important quantities for the environmental comfort, using wireless communication, and allowing data to be displayed in a place away from the monitored poultry house. The possibilities for the use of these networks of sensors and actuators are immense, leaving the user to define his needs to make the choice and programming of sensors and actuators to meet those needs.
