The development of information technology has driven innovation in security systems, one of which is the development of door security systems based on the Internet of Things (IoT) and Radio Frequency Identification (RFID). This research aims to design and implement a Smart Door Lock system that allows real-time and remote access control through the integration of IoT and RFID technology. The system is designed using the ESP32 microcontroller connected to the MFRC522 RFID module, a relay for controlling the door lock, and indicators in the form of a buzzer and LED. Access data is stored locally and can be sent to a Telegram application via the Telegram Bot API to provide notifications of door activity. This research uses a Research and Development (R&D) method to produce a reliable, user-friendly, and efficient security system prototype. The test results show that the system successfully restricts access only to users who have registered RFID cards, and is able to automatically send access notifications to Telegram. Thus, this system can enhance security and convenience in door access management.
