Rationale

Ultrasonic sensor makes use of the characteristics of sound waves to provide a non-contact and accurate USAGE PATTERN
detection scheme for the state and distance of objects.
The sensor transmits mechanical sound waves with high frequency, and receives the sound waves reflected by
the object. By calculating the time or energy between transmitting and receiving sound waves, the accurate
distance or state of the target object can be obtained. Ultrasonic sensors are different from ordinary proximity
switches and photoelectric sensors. Compared with inductive or capacitive proximity switch, its detection
distance is longer. Compared with photoelectric sensor, it can be used in worse environment, and is not affected
by the color of the target, dust and water mist in the air Quick Selection

Ultrasonic sensors are suitable for detecting objects in different states, such as liquid, transparent materials,
