This article presents the development of an energy automation and monitoring system based on Internet of Things technologies, aimed at optimizing electricity consumption in university classrooms. The proposed solution employs two ESP32 microcontrollers and sensors for temperature, luminosity, motion, voltage, and current, integrated into a control architecture that manages lighting and air conditioning systems. The system was validated in a pilot classroom through real energy consumption measurements taken over two consecutive 15-day periods, before and after automation. The results indicate a 16.32% reduction in lighting energy use and a 22.29% reduction in air conditioning, without compromising the functionality of the academic environment. The system demonstrates technical and economic feasibility, with potential for replication in similar educational settings. This work contributes to institutional energy efficiency through a scalable, low-cost solution aligned with sustainability and modernization goals in the education sector.
