Abstract :

In this paper, a low-cost ultrasonic radar system based on Arduino microcontroller was developed. It utilizes ultrasonic sensors to detect the object in range and passes the information to the Arduino microcontroller. When an object is detected, two sets of alarms are triggered. Graphical display on a computer screen was used to illustrate this design. The graphical display uses the position of the detected object on the computer screen to send visual alarm on LED (Light Emitting Diode) screen. Sound alarm can also be sent via an audio buzzer. Adjusting the rotation of a servo motor allows the sensor to detect objects in range between 0and 150˚. Objects up to 40 cm away from the ultrasonic sensor can be detected. The prototype of the design was implemented and coding for Arduino microcontroller was developed. Experimental results show that the system can detect objects with the specified range (40 cm away from the ultrasonic sensor) and alarm was successfully triggered.
