Ultrasonic sensors are devices for detecting the distance to an object. The sensors
use transducers to send pulses and relay back info about the proximity of an object. When using ultrasonic sensors, they send sound waves using frequencies that are above a person's hearing range. Besides, the transducer of the sensor also serves as a microphone to receive the echo. Then, the sensor calculates how far the object is. The main principle used on the ultrasonic sensor is relatively simple. Send a pulse at a frequency of 40kHz that moves via the air and if it encounters an obstacle, it will be reflected back. Using the travel time and speed of sound, the sensor determines the exact distance of the object. Ultrasound sensors are used to detect motion to prevent collisions, especially when using robots that move very fast or often. Other areas of application include drone operations, water level assessment, grain level evaluation, and aviation.
