Ultrasonic Distance Sensor: Range, Frequency, and Transducer Selection Guide
An ultrasonic distance sensor is a non-contact measuring device used to detect the distance between the sensor and a target object. It works by sending ultrasonic sound waves toward the target and receiving the reflected echo. Because it does not require physical contact, this type of sensor is widely used in industrial automation, level monitoring, object detection, parking assistance, robotics, and other measurement systems.
