The advancement in technology has led to the development of various smart systems for enhancing security measures. This project focuses on designing a Door Locking System integrated with an Intruder Alert System using Raspberry Pi. The system utilizes various components such as a Raspberry Pi Zero W, SD card for storage, Pi camera for capturing images, a buzzer for audible alerts, LCD display for visual feedback, servo motor for locking/unlocking mechanism and a keypad for secure access control. The Raspberry Pi acts as the central processing unit, interfacing with these components to provide a robust and intelligent security solution. The system operates in two primary modes: lock/unlock mode based on authenticated access through the keypad and alert mode triggered by unauthorized access attempts detected by the Pi camera and motion sensors. Key functionalities include real-time monitoring of the door via the Pi camera and the ability to remotely control access to the door through secure authentication mechanisms. The integration of these components ensures a reliable and efficient security system suitable for both residential and commercial applications. This project demonstrates the effective use of Raspberry Pi in conjunction with various sensors and communication modules to create a sophisticated yet user-friendly door locking and intruder alert system.
