Abstract — Smart Door Lock IoT
office environments, with scope for future enhancements to improve scalability and real-world deployment. Keywords – Internet of Things, Smart Door Lock, ESP32, Face Recognition, Remote Access, OLED Display, Home Security.
Operational Methodology & Framework
Traditional mechanical door locking systems rely on physical keys and manual control, offering limited security and flexibility. Such systems are prone to key loss, duplication, and unauthorized access, making them insufficient for modern residential and commercial security requirements. As safety concerns increase, there is a growing demand for intelligent access control systems that can provide enhanced protection, automation, and user awareness.
Experimental Findings & Validation
The rapid development of the Internet of Things (IoT) has enabled interconnected devices capable of real-time monitoring and remote control. When combined with artificial intelligence techniques, IoT-based security systems can offer intelligent decision-making and reliable user authentication. Among various biometric methods, facial recognition Figure 1: Conceptual Model & Experimental Workflow for Smart Door Lock Iot 2. System Architecture & Functional Block Diagram Despite numerous advancements, many existing smart door lock systems suffer from limitations such as the absence of robust authentication mechanisms, restricted remote accessibility, or lack of real-time user feedback. Additionally, several systems fail to provide intuitive visual indications regarding access status, reducing usability and situational awareness for users.
