Implementation of Motion Sensors and Buzzers on Robots to Detect Object Movement

Technological advances in this modern era have brought many significant changes in various fields, including security and surveillance. One innovation that stands out is the use of robots to detect object movement. This research aims to implement motion sensors and buzzers on robots to detect the movement of objects around them. This system uses a Passive Infrared (PIR) sensor to detect changes in infrared radiation produced by object movement, and a buzzer as an auditory warning device when movement is detected. In addition, the robot is designed to operate automatically by identifying movement in certain areas. This research also evaluates the effectiveness of the system in detecting objects in various environmental conditions, such as light intensity and sensor detection angle. The results of this implementation show that the PIR sensor is able to detect object movement with good accuracy within a radius of 3 - 4 meters, while the buzzer succeeds in providing a fast and clear auditory response whenever movement occurs. This system can be further integrated with other components for the development of security robots or other smart robots.
