Abstract—The increasing demand for intelligent home security solutions has led to the adoption of Internet of Things (IoT) technologies in access control systems. Theproject proposes an IoT smart door system that integrates  motion detection, facial recognition, and RFIDauthentication to enhance safety and automation. A PIR sensor is used to detect human movement near the door after which a camera module captures the facial image of the individual. Facial authentication is performed using cloud-based recognition techniques. In addition, an RFID module is incorporated as an alternative and supplementary authentication allowing authorized users to gain access through registered RFID tags or cards. Access is granted only when valid credentials are verified through either facial recognition or RFID authentication, while unauthorized attempts are restricted and instant alerts are generated. The system is implemented usi g an Arduino Uno, providing a cost effective, reliable, and scalable security solution for modern residential environments.
