Comparative Study of Burst And Beams Types Ultrasonic Sensor For Distance Measurements

Ultrasonic sensor is one of most popular sensor type to be used in distance measurement. This sensor generates sound waves to measure the distance between itself and the measurement object by using the calculated time of the waves when the waves are reflected back to the sensor. This research is conducted to do a comparative study between 2 types of ultrasonic sensor based on their generated sound waves. The first sensor is Devantech SRF235 which uses a beam type of signal for measurement, and the second is Parallax PING))) which uses burst type of signal. The results show that SRF235 is capable to measure the distance of a small object while the burst type Parallax PING))) has an error approximately of 11.122%.
