SIGHA: AN INTELLIGENT SYSTEM FOR REMOTE MANAGEMENT OF SCHOOL SCHEDULES AND BELL ALARMS BASED ON ESP32

Abstract

The automation of school bell systems is an effective alternative for reducing human errors, improving punctuality, and optimizing schedule management in educational institutions. In this context, this study presents the development and evaluation of the Intelligent School Schedule and Alarm Management System (SIGHA), an embedded solution based on the ESP32 microcontroller, integrated with an RTC DS3231 module, a 16×2 LCD display, and a solid-state relay (SSR), featuring a responsive web interface for remote configuration and monitoring. The research is characterized as applied, qualitative, and experimental, encompassing requirements analysis, system development, functional validation, and a preliminary usability evaluation. The results demonstrated the successful integration of hardware and software components, enabling automatic bell activation, Network Time Protocol (NTP) synchronization, persistent storage of schedules, and remote management of school timetables. The preliminary usability evaluation indicated positive perceptions regarding ease of use, functionality, interface design, and overall usefulness, highlighting the system's potential for application in educational environments. It is concluded that SIGHA represents a reliable, low-cost, and user-friendly solution for automating school schedule management by combining embedded systems, wireless connectivity, and remote management features into a single platform.
