Arduino Radar System

 

What Is Arduino Uno ?

          The Arduino Uno is a computing platform board that is based on input and output

program language that implements the processing language.

The card can be connected to a computer by implementing the associated drivers, or it

may be operated as a stand-alone device.

What is Ultrasonic Sensor ?

                                                           The ultrasonic sensor is a sensor used to detect an object using Sound waves. Ultrasonic sensors detect the object from echoes of sound waves. Ultrasonic sensors generate high frequency sound waves and received the echo. The four pin ultrasonic sensor used in this project to detect the position of an object accurately within a range of 3 cm to 4 meters, but fails to catch the echo when the body is less than 3cm from the device. The device is powered by a 5 volt supply and 14 mA of current. The ultrasonic sensor has been chosen because of its simple design, high power output ,low power input, noise rejection, automatic calibration and cost effectiveness.

Ultrasonic Radars in a Real-time Distance Detection

Ultrasonic Detection.

                                 Ultrasound is defined as a sound in a high frequency range greater than 20 kHz. This is in the upper limit of audible sound range for humans. The detection of object is possible without making contact with object can be done with a variety of methods, including the use of ultrasonic radars. Many applications for this purpose include transmitters and receivers that use infrared light. The detection of object can be easily achieved. However, motion detection of objects or living beings poses interesting and new challenges. This is in the domain of devices such as cameras, radars and detectors that help in industrial robotics and auto guidance systems used in modern world.

WORKING PROCEDURE

                                                    This University level Project Consists of Ultrasonic Sensor, Arduino Uno, servo Motor,  and a PC system. An Ultrasonic Sensor is connected to the Arduino so that when the sensor senses any object, the signal from the sensor is sent to the Arduino. The Ultrasonic sensor emits a high frequency sound waves at regular time intervals as the velocity of sound in air. The waves fall on the object and get reflected back to the receiver. The sensor emits the waves of frequency about 40KHz and it can cover up to a range of 2m. The transmitter that is present in the sensor coverts the electrical signal into ultrasounds whereas the receiver converts the ultrasounds into electrical signal. And, the Ultrasonic sensor which is attached to the servo motor which  can turn up to 180 degrees .The pulse signal is provided by Arduino to the ultrasonic sensor which receives the pulse signal and then reflects back the ultrasonic wave in the forward direction. The onboard microcontroller on the ultrasonic sensor converts the echo into time in microseconds. This time differential is fed to the main microcontroller to find out how long the echo take to return to the sensor, which is a direct function of the distance measured. The pulsing time can be adjusted according to the needs of the user. For detecting moving targets etc.

 CONCLUSION

When the object is detected, the screen will display the presence of the object and the angle and distance of the object will also be displayed. As shown in fig in above.
