- IoT-based environmental monitoring system for heat stress assessment in livestockPublication . Octaviano, Henrique Piscioneri; Leitão, Paulo; Vieira, Frederico; Souza, Wesley Angelino deThis thesis presents the development and evaluation of a low-cost Internet of Things (IoT) system for monitoring environmental parameters related to heat stress in indoor livestock facilities. Commercial solutions are often costly and inflexible, limiting adoption on small and medium-sized farms. To address this gap, this work proposes an integrated system using affordable IoT technologies structured in three layers: a sensor layer with fixed and mobile nodes, a service layer using Node-RED and InfluxDB, and an interface layer with Grafana dashboards. The system includes grid-powered nodes, battery-powered nodes achieving 23 days of autonomy, and a prototype collar node with LoRa communication. It successfully integrates temperature, humidity, black globe measurements, and external weather data to calculate thermal comfort indices (THI and THIadj) in real-time. Experimental results demonstrated reliable data acquisition, visualization, and alerting capabilities. This research contributes a scalable, cost-effective solution for livestock environmental monitoring applicable to various facility sizes. Future work includes finalizing the LoRa collar prototype, field testing, expanding sensor integration, and implementing AI-based predictive analytics.
