Applications of Ultrasonic Sensors

Applications of Ultrasonic Sensors

Ultrasound is a mechanical wave with an extremely short wavelength. The wavelength in the air is generally shorter than 2cm (centimeter), and it has great penetrability to solids or liquids. Therefore, the scope of application is also very wide, and can be applied in the following aspects:
