 Description: Ultrasonic sensor is a transducer that converts ultrasonic signal to other energy signals (usually electrical signals). Ultrasonic wave is a mechanical wave with a vibration frequency higher than 20KHz. It has the characteristics of high frequency, short wavelength and small diffraction phenomenon, especially good directional, being able to become a ray and directional propagation. Ultrasound has great penetrating power to liquids and solids, especially in opaque sunlight. When ultrasonic meets impurity or interface, it will produce significant reflection, form reflection to echo, and encounter moving object can produce Doppler effect. Ultrasonic sensors are widely used in industry, national defense, biomedicine and so on.
