Design and Development of Key Management System (KeMas) Using RFID Based on Arduino Mega 2560 Pro and NodeMCU

Abstract

Key Management System (KeMas) is successfully designed to overcome lecture room/lab key lost problem and unidentified key user in Electrical Engineering Department, Politeknik Sultan Haji Ahmad Shah (POLISAS), Pahang, Malaysia. This project has been developed in line with industry 4.0 (IR 4.0) revolution by using internet of thing (IoT) technology. The design of KeMas is done using Arduino Mega 2560 Pro as microcontroller and ESP8266 NodeMCU Wi-Fi module which sends data over the cloud. KeMas also utilizes the Telegram chat application bot as notification and monitoring the retrieval and return of the keys. KeMas is equipped with an RFID reader as a sensor. Once the user swipes his or her identification card, the key is allowed to be taken and a signal will be sent to the Telegram application through mobile phone to notify the name of the person who takes the key and the name of the room/lab key that he or she took. Subsequently, when the key is returned, notification will also be sent via the Telegram application. Hence, users will always get the latest information on the availability of the keys. KeMas is proven to be effective in solving the key lost problem in Electrical Engineering Department, Politeknik Sultan Haji Ahmad Shah (POLISAS).
