1 Piece 27mm Piezoelectric Transducers Piezoelectric Sensor , Piezo Transducer RF Remote Control Transmitter Switch This gives the added benefitA 27mm piezoelectric Transducer sensor or element is a device that uses the piezoelectric effect, it is basically a device which converts voltage to vibration and vibration to voltage. It normally comes in handy to measure knock (knock sensor) or vibration (vibration sensor).
