        abstract = {In the rapidly evolving domain of industrial automation, traditional environmental monitoring systems are often constrained by high wired infrastructure costs, limited scalability, and a lack of remote accessibility. To address these limitations, a scalable Internet of Things (IoT) framework is proposed for real-time environmental monitoring and industrial load control. The primary objective of this research is to develop a low-latency, cost-effective system that bridges the gap between physical sensor networks and digital supervisory interfaces. The methodology involves the utilization of the ESP32 microcontroller as the central gateway, interfacing with DHT11 sensors for the acquisition of temperature and humidity data, and multi-channel relay modules for the actuation of distinct loads, including a Peltier cooling unit, a heating element, and a stepper motor-driven conveyor belt.
Data transmission is facilitated by the Message Queuing Telemetry Transport (MQTT) protocol via the HiveMQ broker, ensuring efficient bandwidth usage and reliable connectivity in constrained networks. A key contribution of this work is the integration of this hardware architecture with Ignition SCADA (Supervisory Control and Data Acquisition), a standard industrial software platform, to create a sophisticated graphical user interface for centralized data visualization and command execution. The system is evaluated based on response time and reliability, demonstrating successful bi-directional communication. The expected outcome is a modular, robust architecture suitable for deployment in diverse applications such as smart agriculture, cold storage management, and industrial safety monitoring.},
