Desenvolvimento de rede de sensores para monitoramento da concentração de gases em aviários

Abstract

Poultry farming has a prominent place in the country's agricultural production, being a booming activity and having a large representation of the national economy. With this expansion comes also the technological and scientific development that involves all the productive links of this chain. The poultry houses feature one of these links, where birds grow in climate-controlled environments, controlled by monitoring and automation systems. One of the risks that these environments pose is the high concentration of gases harmful to the health of both birds and workers of these units, making it a concern for poultry activity. The general objective of this study is to develop a sensor network capable of monitoring the concentration of the main gases found in the internal atmosphere of the poultry house. This sensor network was developed from open-source solutions and low-cost equipment, from the construction of prototypes responsible for data collection to the implementation of the monitoring system. The prototypes were tested in a commercial aviary in the city of CascavelPR, and the observed results show that the sensor MQ-135 obtained greater assertiveness in monitoring the conditions of ammonia gas compared to MQ-137. The mesh wireless network using software implementation showed instability during the evaluation period. The web monitoring system, with the developed colorimetric map component, was fundamental for presenting the results to the rural producer, as it facilitated the interpretation of the information.
