The ProGuard" is an innovative security system that utilizes radar technology and ultrasonic sensors to enhance access control and safety. This system is equipped with two ultrasonic sensors that detect the presence of unauthorized individuals in a designated area. Upon detection, ProGuard automatically initiates a door-closing mechanism to prevent unauthorized access. This system offers a reliable and efficient solution for securing premises, ensuring that only authorized personnel can enter sensitive areas. The design and functionality of ProGuard make it suitable for various applications, including residential, commercial, and industrial settings, providing a proactive approach to security management. This abstract outlines the core features of the ProGuard system, its operational principles, and its potential benefits in enhancing security protocols.
