DADISICK Ultrasonic sensor
Ultrasonic sensors use the characteristics of sound waves to provide a non-contact, accurate detection solution for the state and distance of objects. By transmitting high-frequency mechanical sound waves and receiving sound waves reflected by the object, the precise distance or state of the target object is obtained by calculating the time or energy between the transmission and reception of the sound waves.
Ultrasonic sensors are different from ordinary proximity switches and photoelectric sensors. Compared with inductive or capacitive proximity switches, it has a longer detection distance, and compared with photoelectric sensors, it can be used in harsher environments and is not affected by the color of the target object and dust and water mist in the air. Ultrasonic sensors are suitable for detecting objects in different states, such as liquids, transparent materials, reflective materials, and particulate matter.
