Abstract

This research develops a secure key management system prototype by integrating Radio Frequency Identification (RFID) and keypad technologies to enhance the protection of safes. Safes are widely used for storing valuable assets, but traditional locking systems are vulnerable to unauthorized access. The system combines RFID for user identification and a keypad for password entry, providing a dual-layer security mechanism. The methodology involves a prototyping approach, allowing iterative development and refinement of the system. The system utilizes Arduino Uno as the main controller, with additional hardware components such as an RFID reader, keypad, LCD, and servo motor for door control. Testing of the system demonstrates successful functionality, including identification of valid and invalid RFID tags, password verification, and access control through the servo motor. The results show that the system significantly enhances the security and convenience of accessing the safe, minimizing the risk of unauthorized entry. Future improvements include the development of a user interface for easier password management and full-scale implementation on real safes.

Abstract

This research presents the design and development of an automatic granule weighing system based on a microcontroller, integrated with a TFT-based Human Machine Interface (HMI). The system aims to enhance accuracy and efficiency in the weighing process of granular raw materials, particularly in small- to medium-scale industries. It utilizes a load cell sensor and HX711 module for precise weight measurement, a vibrating motor to ensure consistent material flow, and a servo motor to control the dispensing valve. The HMI enables users to set target weights, adjust vibration speed, and monitor real-time data. Testing was conducted using rice granules with three different speed modes (low, medium, and high) and eight target weight variations. The system achieved an average error of 0.676% at low speed, 0.184% at medium speed, and 0.542% at high speed, with an overall accuracy of 99.533%. The integration of automated weighing mechanisms with an intuitive HMI demonstrates the system’s potential for industrial applications requiring precise, reliable, and user-friendly material handling
