Ultrasonic and Arduino Based Radar System

Abstract: With the rapid advancement of automation and sensing technologies, radar systems have become essential for detecting and tracking objects in various applications such as robotics, navigation, and security. The project titled “Ultrasonic Arduino-Based Radar System” aims to design and implement a cost-effective and efficient radar prototype capable of detecting the distance and position of objects using ultrasonic technology integrated with Arduino microcontroller. In this system, the HC-SR04 ultrasonic sensor emits ultrasonic waves to measure the distance of surrounding objects based on the time delay of the reflected signal. The Arduino UNO processes this information and controls a servo motor to rotate the sensor within a specified angle, enabling area scanning. The detected data is displayed visually on the processing IDE or Blink application, representing real-time radar output on a graphical interface. The project involves major stages such as hardware interfacing, data acquisition, signal processing and real-time visualization. This radar system helps in object detection and environment mapping, providing practical applications in areas such as robotics, defence, obstacle avoidance and automation systems. It effectively demonstrates the integration of electronics and programming for smart detection solutions.
