The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.

Ultrasonic sensors are used as animal repellents. There are some sensors that are designed to only genereate ultrasound when an animal is detected with the motion sensor.
There are many types of level sensors you can use to measure the water level in a tank such as submersible level sensor, ultrasonic level sensor, float level sensor. If you are searching for a level sensor you visit our website iconprocon[dot]com
principle refers to the basic objective of something. Operation refers to how it operates.
Any Sensor has to have an electrical connection to transmit signals from the sensor the the VDU. however it is a DC connection varying in Voltages between 24 and 120V, and current would be 4 to 20 mA
An ultrasonic motion sensor is a device that uses high-frequency sound waves to detect movement within its range. When an object moves in the vicinity of the sensor, it reflects the sound waves back to the sensor, which triggers a response or alerts the system to the motion. Ultrasonic motion sensors are commonly used in security systems, automatic doors, and occupancy detection systems.
piezo electric principle
Ultrasonic interferometers use the principle of interference of sound waves to measure the velocity of sound in a medium. By creating standing waves and analyzing their interference pattern, these interferometers can accurately determine the speed of sound in the medium.
An ultrasonic sensor is used to measure distances by emitting ultrasonic waves and then calculating the time it takes for the waves to bounce back. It is commonly used in robotics, parking sensors, object detection, and distance measuring applications.
Ultrasonic imaging uses high-frequency sound waves to create detailed images of internal body structures. The principle is based on the reflection and absorption of sound waves by different tissues, which are then processed to generate a visual representation. Ultrasonic imaging is widely used in medical diagnostics due to its non-invasive nature and ability to provide real-time information.
There is the main robotics brick, four wheels, two balls, ultrasonic sound sensor, touch sensor, light sensor, sound sensor, cables, and many other bricks
two types one is ultrasonic and other is ir sensors
Many - fish finders, many sonar devices.
