Perancangan Alat Bantu Parkir Menggunakan Sensor Ultronik dan Arduino Uno

Abstract

The purpose of this measurement is to determine the distance of a media using sound wave reflection method that is compared to the time interval . The test results showed that a distance can be obtained by searching the physical speed (sound) that is monitored by HC - SR04 ultrasonic sensor . In general , this tool will fire ultrasonic waves toward an area or target. After touding the surface of the target , then the target will reflect back the wave. Wave reflection from the target to be captured by the sensor , then the sensor calculates the difference between a transmitting and a reflected wave is received.
