Nanjing KJT Electric Co,.LTD
Ultrasonic sensors use the characteristics of sound waves to provide a contactless and accurate detection solution for detecting the status and distance of objects. By emitting mechanical sound waves with a high frequency, the sensor receives the sound waves reflected back from the object. By calculating the time or energy between the emitted and received sound waves, the precise distance to the target object is obtained.
