The Iot-Based Smart Lecturer Locker System Design

Abstract

The growing application of Internet of Things (IoT) technologies brings new opportunities to modernize conventional systems across various sectors including home, business and administrative. At Polytechnic Sultan Haji Ahmad Shah in Kuantan, the conventional lecturer locker system remains largely manual, requiring lecturers to check their assigned lockers for mail or student assignments, an approach that is both time- consuming and prone to oversight. This project introduces the IoT based Smart Lecturer Locker System, a modernized locker system designed to enhance efficiency and reduce manual intervention through smart automation. Built using an ESP32 microcontroller, infrared sensors, and a Wi-Fi module, the system detects assignment submissions and sends real-time notifications to lecturers via Telegram. Students can submit documents without direct interaction, as a front-facing sensor captures each insertion. A key innovation of the system is its dual-compartment design: an “early” slot for on-time submissions and a “late” slot that activates automatically after the lecturer-defined deadline, facilitating easy tracking of submission punctuality. The Smart Lecturer Locker System offers a secure, intelligent, and efficient solution for assignment management, supporting both academic productivity and accountability. Experiment results demonstrate the feasibility, usability and effectiveness of the smart locker system in a real academic environment. The paper discusses system architecture and implementation process. Future enhancements may include integration with academic management systems, support for varied document formats, and an improved user interface.
