Authors : Kutluca Muhammed Emin . şahi̇n Mustafa Ergin .
Abstract
This study introduces a smart doorbell system that enhances the safety and independence of hearing-impaired individuals. The system delivers customizable vibration and light-based notifications through a mobile application, ensuring that users are promptly informed of visitors at their door. In addition to real-time alerts, notifications are stored in the app for later review, and a backup power supply ensures uninterrupted operation during electricity outages. The system was validated through both simulation and real-world testing, confirming stable performance, quick response times, and reliable wireless communication. Designed to be affordable and energy-efficient, the proposed solution not only improves daily convenience for hearing-impaired individuals but also offers potential for wider use in assistive technology applications.
