Abstract: This paper presents the development and implementation of a smart door mat utilizing face recognition technology. The primary goal of this project is to enhance improving accessibility for users, offering a hands-free entry solution, and strengthening home security by logging visitor data. The project emphasizes usability, reliability, and scalability, making it suitable for residential and commercial applications. The system integrates a face recognition algorithm implemented in Python using the OpenCV library, with adjustments controlled by an Arduino through serial communication.

Keywords: Piezoelectric Sensor, Smart Doormat, Visitor Detection, Home Automation, IoT Integration, Energy Efficiency
