A Review on Object Detection Radar Systems Using Arduino Uno

Abstract: This project presents an Object Detection Radar System based on the Arduino Uno, designed to detect and visualize the position and distance of objects within a specified range using ultrasonic sensors and servo motor rotation. The system provides a cost-effective solution for detecting obstacles or intrusions by mimicking radar functionality. Using an HC-SR04 ultrasonic sensor, the system measures the distance to nearby objects by transmitting and receiving ultrasonic waves. A servo motor rotates the sensor to scan the area in front of it, while Arduino Uno processes the data and transmits it to a computer or Android device for visualization through Processing software or a mobile interface. This real-time radar visualization enhances awareness of surrounding objects and can be applied in areas such as robotics, surveillance, and autonomous vehicles. The proposed system demonstrates how low-cost embedded components can be used to replicate the principles of radar for educational, security, and automation purposes.
