This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

Ultrasound transducer technology forms a cornerstone of modern diagnostic and therapeutic systems, harnessing piezoelectric materials to convert electrical energy into acoustic waves, and vice versa.

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
