Piezoelectric ultrasonic transducer introduction
Many applications of ultrasonic sensors are based on distance measurement, such as UAV obstacle avoidance, rangefinders, parking radars... In these applications, the role of ultrasonic transducers as an important component is energy conversion. The ultrasonic transmitter converts the pulse signal into ultrasonic waves and transmits it, and the ultrasonic receiver receives the returned ultrasonic waves and converts them into electrical signals.
