The radars have become the “eyes” of electronic devices and the
use of radar has become increasingly popular in various fields of study.
At the same time, these devices can also be used to assist people in all the
fields the life. Ultrasonic radars can accomplish distance measurements
by measuring the time delay between the emission of the ultrasonic signal
and receipt of the echo signal. Microcontrollers can be connected to
perform computations or control timers in these devices. The detection of
the distance between the objects (targets) poses a challenge on the
temporal resolution of the detector. The correct calibration of these radars
is imperative given the fact that the safety of the user depends on the
This goal of this project is the use of Ultrasonic Sensor by
connecting to the Arduino UNO R3 board and the signal from the sensor
further provided to the screen formed on the laptop to measure the
presence of any obstacle in front of the sensor as well as determine the
distance, range, and angle at which the obstacle is detected by the sensor.
In this study ultrasound sensor worked as a radar. The use of the Arduino
software to design a radar system because Arduino has more advantages
It is an open-source project, software/hardware is
extremely accessible and very flexible to be customized and a
It is easy to use, connects to computer via USB and communicates
using standard serial protocol, runs in standalone mode and as
interface connected to PC/Macintosh computers.
It is cheap.
Arduino is backed up by a growing online community, lots of
source code is already available and we can share and post our
examples for others to use.
This project is about Radar System controlled via Arduino. This
RADAR system consists of an ultrasonic sensor and servo motor. Ultrasonic sensor is attached to the servo motor it rotates about 180 degrees
and gives a visual representation of the software called processing IDE.
Processing IDE gives graphical representation and it also gives an angle
or position of the object and the distance of the object. This system is
controlled through Arduino.
Radar (sonar) able to detect the presence of fixed and moved
targets and can determine the distance between it and the targets in
different angles (0-180)0 which is the range can sweep by TowerPro
SG90 Servo used in this project.
The detection of objects (targets) doesn't depend on the type of the
material that the target made from it; it can detect all the types of objects
in the range.
It is very important to use these techniques for security in
government offices, street, banks, and so and instead of the camera
system because it is more accurate, not affected by the weather conditions
like (rain , snow, and fog).
