An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves and converts the reflected sound into an electrical signal. Ultrasonic sensors use transducers to send and receive ultrasonic pulses that relay back information about the proximity of objects. High-frequency sound waves reflect off the boundary, creating a distinct echo pattern. Ultrasonic sensors have two main components: a transmitter (which uses piezoelectric crystals to emit sound) and a receiver (which receives the sound as it reaches and exits the target). Datavision offers a wide range of ultrasonic sensors such as ultrasonic water level sensors, ultrasonic range sensors, etc.
