Distance measurement and continuous recording when done manually can be tedious and predictable errors in recording. For it will do design a device capable of measuring and recording automatically. Tools that will be made using the ultrasonic sensor and microcontroller ATMega 8535 as a main components. Ultrasonic sensors to detect objects in front of about distance of 3 cm until 3 meters. The reflection of ultrasonic waves to be received back by the sensor, so that the ATMEGA85 microcontroller will know when the ultrasonic wave is emitted until it is received back. And then the microcontroller will processed and displayed on the LCD and sent to a computer for display with the time of recording. Keywords : Measurement, sensor ultrasonic, microcontroller, data logging.
