In this paper the study of smart automation system remotely controls and monitors industrial appliances using Long Range Wide Area Network (LoRa WAN) technology. The work presents a novel smart automation system, leveraging Long Range Wide Area Network (LoRaWAN) technology to remotely control and monitor industrial appliances. The proposed system integrates a wireless communication framework, sensor nodes, and a user-friendly smartphone application. Utilizing the ESP32 module, the system establishes a reliable communication link between the smartphone and LoRa module, facilitating seamless control and monitoring. The system efficiency is evaluated through three real-world case studies, demonstrating its capability in appliance switching control, fire detection, and ambient temperature and humidity monitoring. Results show an impressive accuracy of 92.33% and operational range of 3–12 km. The system’s adaptable design and low power consumption render it an ideal solution for smart automation applications.
