How Do Ultrasonics Work at Mackenzie Boehm blog

How Do Ultrasonics Work. These waves travel through the air until they encounter an object, at which point they are partially reflected back to the sensor. As they vibrate, they push and pull the air around them, producing ultrasound waves. The longevity and popularity of ultrasonic sensors is attributable to the fact that they are inexpensive, adaptable, and usable in a variety of applications. Crystals of some materials (such as quartz) vibrate very fast when you pass electricity through them—an effect called piezoelectricity. It sends out ultrasonic waves, which bounce back after hitting something, and then figures out how long it. The ultrasonic sensor works by bouncing sound waves off stuff to check distances and find objects. Unlike audible sounds, ultrasonic sensors operate at frequencies exceeding the human hearing range, typically ranging from 20 khz to 200 khz. Devices that produce ultrasound waves using piezoelectricity are known as piezoelectric transducers.
