Ultrasonic Receivers, TransmittersUltrasonic receivers and transmitters are sensors that are used to detect or measure objects using ultrasonic sound waves. Ultrasonic sensors work by emitting a high-frequency sound wave and measuring the time it takes for the wave to bounce back after striking an object. This time-of-flight measurement is then used to calculate the distance to the object. Ultrasonic receivers and transmitters are commonly used in applications such as industrial automation, medical imaging, and security systems. They are often used in conjunction with other sensors, such as cameras or infrared sensors, to provide a more complete picture of the environment or object being measured.
