Abstract
Environmental monitoring schemes have been transformed by the incorporation of IoT technologies in industrial environments, enabling a shift toward continuous monitoring models and immediate response to risk situations. However, many available solutions rely on highly complex and costly SCADA infrastructures, which limits their adoption in facilities with budgetary constraints. In this context, the present research posed as its central question whether it is possible to design and implement a low-cost IoT system, based on open-source technologies, capable of providing real-time environmental monitoring with immediate acoustic alerts and reliable remote notifications. To address this question, an experimental architecture was developed based on Arduino and ESP32 platforms, integrating temperature and gas sensors, a DFPlayer Mini module for customized acoustic feedback, and a wireless transmission scheme to a remote platform. The system was validated through controlled tests involving the exceedance of critical thresholds, evaluating detection accuracy, alert activation latency, and communication stability during continuous operation. The results showed a correct detection rate above 95%, an average alert activation time below 1.5 s, and remote transmission stability greater than 97%. In addition, an approximate 40% reduction in operator response time was observed compared to traditional manual schemes. Consequently, the study demonstrates that an open and scalable IoT architecture can achieve adequate performance levels for industrial safety, contributing a robust human–computer interaction approach and establishing a solid foundation for future extensions toward predictive and interoperable capabilities.
