Double Loop Antenna Design For Smart Door Lock System Using Iot Applications

Introduction: The rapid advancements in Internet of Things (IoT) technology have led to the development of smart door lock systems, enhancing home security. This manuscript presents the Design of Double Loop Antenna for Smart Door Lock System using IoT Applications (DLA-SDLS-IoT). The system monitors and secures entry points using sensors, a Double Loop Antenna, and an ESP32-CAM for data processing and communication. It alerts users of unauthorized access and streamlines door lock management via mobile notifications.Methods: The DLA-SDLS-IoT system integrates components including an ESP32-CAM microcontroller, an IR sensor for obstacle detection, an OV2640 camera for facial recognition, and a solenoid door lock. Notifications are sent via Telegram, featuring images and control options. A buzzer alerts users of intruders, and the system uses Wi-Fi for internet connectivity. Programming is done in Python.Results: The DLA-SDLS-IoT system shows significant improvements over existing methods, achieving higher frequencies, lower return losses, and lower Voltage Standing Wave Ratio (VSWR), with a higher gain. These metrics indicate superior signal efficiency and reliability compared to other systems like IoT-SSS-DLA, FA-SDLS-MCM, and SDA-LPDA-SL.Conclusion: The DLA-SDLS-IoT system advances smart door lock technology by integrating IoT for enhanced security and user interaction. It outperforms existing solutions in performance metrics, indicating potential for widespread application. Future improvements could further enhance its functionality and user experience
