Ultrasonic sensor is designed by ultrasonic
characteristics.Ultrasonic is a kind of mechanical wave which
vibration frequency is higher than the sound wave. It has high
frequency and short wavelength, especially the good direction,
Which can transmit to the specified direction and
location.Ultrasonic sensors can used in gas, Liquid and solid.
Ultrasonic has the big ability to penetrate liquid and
solid.Especially in the sunshine opaque solid, it can penetrate
tens meters depth.
Ultrasonic sensors are widely used in car parking assistance,
proximity alarms,Medical ultrasounds, and distance measurement.
