Ali Ramschie, Ronny Katuuk, Fanny Doringin, Sulastri Eksan . Design and Development of an IoT-Based Room Access Security System with Password Authentication and Real-Time Notification. International Journal of Computer Applications. 187, 52 ( Nov 2025), 59-67. DOI=10.5120/ijca2025925891
Abstract
Room access security is an essential aspect of safeguarding both physical assets and sensitive data. Although the use of physical keys and access cards is still common, both methods have their weaknesses. Keys can be lost or duplicated, while access cards are at risk of being misused by unauthorized individuals. Such situations may reduce the level of security, especially if not supported by a reliable monitoring system. Therefore, a more modern and secure technology-based solution is needed to ensure room security through the implementation of an IoT-based access control system. This research designs a room access security system utilizing Internet of Things (IoT) technology, with authentication carried out through password input on a keypad device. If any suspicious access activity occurs, the system will automatically send a notification to the room owner’s smartphone. With this feature, the owner can directly receive information about both authorized and unauthorized access activities. The method applied in this research is prototyping, with a workflow that includes problem identification, data collection, system design, prototype development, implementation, and system evaluation. The results show that the IoT-based room access security system with password authentication via keypad functions properly. When the detected password input is correct, the door will unlock, and the electrical system in the room will be activated. If the password input is incorrect, the alarm will sound, and the system will send a notification to the owner’s smartphone. Consequently, the room owner can disable the password input function via the keypad and also monitor the room condition through CCTV access.
