Ultrasonic receivers converts ultrasonic signals into other energy signals. Ultrasonic wave is a mechanical wave whose vibration frequency is higher than 20kHz. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directions. It can become a ray and directional propagation. The penetration of ultrasonic waves through liquids and solids is strong. Ultrasonic sensors are mainly composed of transmitters, receivers, control parts and power supply parts.
