Range Finder: - With Where the Object Located

Abstract

This paper presents the design and implementation of an Arduino-based range finder system integrated with a servo motor for directional scanning and location awareness. The primary objective of the project is to measure the distance of objects in different directions by rotating a sensor using a servo motor while also enabling the system to access its geographical location through a GPS module. In this system, the Arduino microcontroller acts as the central processing unit, interfacing with an ultrasonic sensor to measure distance and a servo motor to rotate the sensor across a defined angular range. The ultrasonic sensor continuously detects obstacles by calculating the time taken for sound waves to reflect from objects. Simultaneously, a GPS module is used to obtain real-time latitude and longitude coordinates of the system, enhancing its tracking capability.

The servo motor enables 180-degree scanning, allowing the system to collect distance data from multiple directions, which can be used for obstacle detection and environmental mapping. The combination of range finding and location tracking makes the system suitable for applications such as robotic navigation, surveillance systems, and smart obstacle detection. The proposed system is cost-effective, easy to implement, and efficient in real-time operation. Experimental results demonstrate reliable distance measurement and smooth servo-based scanning. This project highlights the practical use of Arduino in integrating sensing, motion control, and location tracking for intelligent embedded system applications.
