Design and Build “Smart Key Tracking Systems with RFID and Arduino Mega” for Use in Petrochemical Engineering Department PTSN

Abstract

The problem concerning key storage at Politeknik Tun Syed Nasir Syed Ismail (PTSN) systems is a lack of systematic administration, leading to uncontrolled and insecure essential management procedures. Consequently, the objective is to create an intelligent key tracking system (SKTS) utilizing radio frequency identification (RFID) and Arduino Mega to establish a secure and properly organized key storage system with efficient data management. This project introduces the monitoring system with automated and real-time data collection. SKTS design uses an Arduino Mega 2560 microcontroller and an ESP8266 Node MCU Wi-Fi module that sends data over the cloud. The project also utilizes the Telegram chat application bot to notify and monitor the keys' retrieval and return. It is also equipped with an RFID reader as a sensor. As the authorized user, once the RFID card is swept, type the selection key number; the solenoid lock for the selected key will open, and the key is free to be picked. The liquid crystal display (LCD) will show the authorized user data and selected room number. A signal will send the information to the Telegram application through a mobile phone to notify the other authorized user. This project successfully achieves its objective by utilizing the Telegram application to notify critical users and authorized individuals when keys are returned. These real-time notifications are visible to all registered group members on the Telegram application. The Likert Scale, which has two points, is established by utilizing data responses from the rubrics form, with evaluators consisting of industrial designers and researchers. The results are subsequently synthesized using qualitative percentages. The responses to the item provided via the rubric assessment form show that the SKTS meets the design, ideal, and functional aspects.
