Abstract

Sonar (Sound Navigation and Ranging) was covertly created by few countries during the reign of World War II. SONAR can be used to detect some moving object. It helps in the measurement of distance and angle from the observer. It works on the principle of Doppler shift. The designing of cheaper SONAR system for security purpose is the requirement of an industry. In this research Paper, the designing and implementation of Arduino based SONAR system using ultrasonic sensor are presented. The device is able to detect the object, calculate its distance (up to 30cm) and can determine the elevation angle. It provides a cheaper solution for security purposes.

Highlights

Sonar (Sound Navigation and Ranging) is a device which can be used for the detection of location of some moving objects
Ultrasonic sensor based Sonars are used for distinguishing the objects and separation of edge
The cutting edge employments of SONAR are profoundly various, including airport regulation, radar cosmology, frameworks including altimetry and air traffic control, guided rocket objective finding, sea reconnaissance, air-safeguard and antimissile, radars operating for marine activities like the observation of ships and boats and the exploration of historic points, from the hostility of flying machines to the crash frameworks, space surveillance and meeting frameworks, meteorological precipitation checking and ground-entering radar for geographical perceptions

Summary

Introduction

Sonar (Sound Navigation and Ranging) is a device which can be used for the detection of location of some moving objects. The UNO R3 is grounded on the basis of ATmega328P and can be classified as microcontroller board It can be entirely used as a microcontroller; it merely requires its connection to the computer through USB port and some sort of power provided by AC-to-DC adapter or you can use battery to get started. It is utilized as an external power source (unlike a typical 5 volts source provided by USB connection or any other controlled power source). Just like Sonar or Radar, these sensors work on the principle which involves the evaluation of the traits of target by interpreting the sound waves or echoes respectively This ultrasonic range (≻20KHz) of sound waves is typically generated by using transducers of the sensors. In this project servo SG-90 motor was used for angular movement of ultrasonic sensors
