The PCB generates a high-frequency electrical drive signal and amplifies its power. It works with a sampling circuit to track the resonant frequency of the transducer, then drives the piezoelectric transducer to vibrate and generate ultrasonic waves in the water. So, it is not simply sweeping through different ultrasonic frequencies; it automatically tracks the transducer’s resonant frequency for efficient operation.
