DESIGN ULTRASONIC RADAR SYSTEM USING ARDUINO UNO

Recently research about ultrasonic radar is growth rapidly and the aim of this system is to detect distance and determine object position in the range of radar (2-300 cm). PING sensor use to transmitter and receiver ultrasonic wave (40 kHz) and the Arduino Uno board controlled spin of radar and servo motor by automatically or manually. Ultrasonic sensor transmitted sounds signal frequency 40 kHz and normal velocity 340 m/s in the air. The experiment result show that ultrasonic radar has accuracy 98,702 and radar needs subjection mean 73 seconds to attain 1-360o. Result of polar coordinates describe surface of the object shape and simulate in 4 differences angle with the distances between object and radar are 17 cm and 34 cm. All object used in this experiment can be detect by radar appropriately in real distance and the color is not influence the result distance in monitoring
