Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals, usually electrical signals. It is an important branch of sensor products and accounts for a large proportion in the entire sensor industry. Ultrasonic sensors are widely used such as:Liquid level measurement: s

The sound wave frequency that human ears can hear is 20HZ～20KHz. When the frequency is higher than 20KHz, the human ear cannot hear it. Therefore, we call the sound wave with a frequency higher than 20KHz "ultrasonic wave".Ultrasound has a strong directivity and travels a long distance in the air.

Ultrasound is a mechanical wave with an extremely short wavelength. It has the characteristics of high frequency, short wavelength, and small diffraction phenomenon. It can propagate directionally and being reflectet when it encounters obstacles. In nature, bats judge and avoid obstacles by emitting

Sensor technology is one of the key technologies supporting the development of the automobile manufacturing industry. With the expansion of the commercial scale of intelligent vehicles, sensors have became the essential components of almost all vehicles. Cars are able to detect surroundings and bli
