Working principle of ultrasonic converter (transducer):
Ultrasonic sensors are sensors developed using the characteristics of ultrasonic waves.
Ultrasound is a mechanical wave with a vibration frequency higher than that of sound waves. It is generated by the vibration of the transducer chip under the excitation of voltage.
It has high frequency, short wavelength, small diffraction phenomenon, especially good directivity, and can become rays and be oriented. propagation characteristics.
