Introduction
Ultrasonic sensor is a kind of sensor developed by using the
characteristics of ultrasonic wave. Ultrasonic wave is a kind of mechanical wave whose vibration
frequency is higher than sound wave. It is generated by the
vibration of energy exchange wafer under the excitation of voltage.
It has the characteristics of high frequency, short wavelength,
small diffraction phenomenon, especially good directivity, and can
become a ray and directional propagation. Ultrasonic on liquid, solid penetration ability is very great,
especially in the sunlight opaque solid, it can penetrate the depth
of dozens of meters. Ultrasonic waves will produce significant reflections when they
encounter impurities or interfaces, and Doppler effects when they
encounter moving objects.
Principle
The ultrasonic distance sensor transmits the ultrasonic pulse to
the measured object, and then returns the echo formed by the
measured object to the receiving sensor, so as to obtain the time
difference between the transmitting and receiving, and then the
distance between the transducer and the measured medium surface can
be obtained according to the sound speed in the medium. So we can calculate the distance between the transducer and the
reflector of the medium D=C*t/2, divided by 2 because the
ultrasonic wave travels twice the distance between the transducer
and the medium when it is transmitted and received. (D is distance, C is speed of sound, and t is time).
