The research provides a security system that achieves automatic object sensing detection at a given radius range from the security system. This system provides an automatic detection of intrusion into a restricted property. An ultrasonic range sensor and a stepper motor are interfaced with a microcontroller. The range sensor is mounted on top of a stepper motor which rotates about its axis continuously, and emits a burst of energy until reflected off of an object. When the range sensor senses an object, the angle of the stepper motor at the instance of object detection is recorded by the microcontroller and displayed on a Liquid Crystal Display (LCD) along with the object distance. Because of the rotational motion of the sensing system, it can be concluded that this system is quite different in its approach to security issues as compared to similar ones that which are just stationed in a fixed point and meant to detect obstacle or intrusion from a particular direction.
