Abstract

The Smart Door Lock leverages advanced facial recognition technology to enhance access control. This system replaces traditional keys or passwords by recognizing and verifying individuals through facial feature analysis. It utilizes the ESP32- CAM module, an affordable development board equipped with a camera, Wi-Fi, Bluetooth, and low- energy BLE capabilities. Its compact structure makes it well-suited for IoT applications. When an authorized individual approaches, the door unlocks automatically, offering both security and ease of use. The setup also incorporates an Arduino Uno microcontroller, capable of handling multiple inputs and outputs for added flexibility. For improved security, an optional fingerprint sensor can be integrated, enabling dual-layer authentication through biometric verification.
