Abstract
This study describes the development of a secure and affordable password-based smart door lock system built using an Arduino microcontroller. The system combines a keypad for user input, a camera module for monitoring, GSM communication for alerts, and a servo motor to control the locking mechanism. Access is granted when a user enters the correct password through the keypad, after which the servo motor automatically unlocks the door. To enhance security, the system sends real-time notifications via GSM and provides local surveillance through the camera module. It is designed to operate independently without relying on a constant Internet connection, making it suitable for areas with limited network availability. The embedded real-time control logic ensures fast response and smooth standalone operation. Experimental results demonstrate that the system is reliable, efficient, and cost-effective, making it a practical solution for improving security in residential and office environments.
