An ultrasound sensor (also called an ultrasonic sensor) is a device that measures the distance to an object by emitting high-frequency sound waves (ultrasound) and detecting the echo that bounces back.

Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.

Mar 29, 2022 · Ultrasonic sensors are used for the detection of distance for an extended range of targets irrespective of the target’s surface, color, and shape. This is all the concept of ultrasonic sensors.

May 20, 2021 · Ultrasonic sensors are commonly used to detect the levels of liquid in a vessel. They are particularly suited to this application because they are unaffected by the color (or absence thereof) of …

Ultrasonic sensors can measure distance and detect the presence of an object without making physical contact. They do so by producing and monitoring an ultrasonic echo.

Feb 1, 2022 · Learn how ultrasonic sensors work, how transmitters and receivers come into play, considerations for choosing an ultrasonic sensor, and their applications.

Ultrasonic sensors measure distances based on transmitting and receiving ultrasonic signals. They can stably detect transparent or complex-shaped targets and have high environmental resistance.

Feb 2, 2026 · MIT researchers developed a miniaturized ultrasound system that could make it easier for ultrasounds to be performed more often, either at home or at a doctor’s office. The system could help …

What Is an Ultrasonic Sensor? Ultrasonic sensors are devices that generate ultra-high-frequency sound waves greater than 20 kHz, beyond the range of human hearing. They use electrical energy and a …

Explore the construction, working principle, and applications of ultrasonic sensors used for distance measurement. Learn about signal transmission, echo reception, and piezoelectric crystals.
