This paper presents the development and implementation of a centralized control system for air conditioning units in an educational institution, using low-cost Internet of Things (IoT) devices based on the ESP32 microcontroller. The solution integrates infrared emitters and receivers to replicate the devices' original commands, connected to a web platform for monitoring, scheduling, and remote activation. The system makes periodic HTTP requests to the server, which verifies compliance between the desired and actual status, resending commands when necessary to ensure synchronization. The methodology included a technical survey of the devices, assembly and programming of the modules, physical installation in the environment, and development of the web interface with a backend and relational database. This database stores device identifiers, infrared codes, and execution schedules, ensuring scalability and traceability of actions. The results demonstrate that the combination of affordable hardware and simple communication protocols can offer efficient solutions for automation and HVAC management in educational environments. Despite limitations, such as Wi-Fi network dependence and line-of-sight requirements for IR transmission, the system demonstrated significant potential for energy savings, improved thermal comfort, and future expansion with additional sensors and support for multiple protocols.
