SENSOR ULTRASONIK SRF05 SEBAGAI PEMANTAU KECEPATAN KENDARAAN BERMOTOR

Ultrasonic sensor function base that is as distance measures. In those ability to measure distance, it possible to use to measure velocity with two ultrasonic sensor. Velocity measuring system is the first measures is how the reflection distance from ultrasonic sensor less than maximum limit monitoring. Sensor will begin to calculated time and when the second sensor obtain reflection time will be stopped. The velocity value that has gotten is result of quotient between both sensor with bounce time between sensor. The velocity value will be displayed on LCD. The velocity value that has measured from this device is not precision enough. In this case cause by delay in this sensor that can influence time calculation to get velocity value. Key word: ultrasonic, Velocity, Measure, sensor, LCD
