Piezo Ceramic Element Sounder Sensor
= Versatile Piezoelectric Disc for Sound Generation and Vibration Detection =
The piezo ceramic element is a versatile electromechanical transducer that converts electrical energy into mechanical vibration (sound) and vice versa, making it ideal for both generating audio alerts and sensing knocks or vibrations.
DualFunction Component Works as a buzzer for sound generation or as a knock/vibration sensor
Simple 2Wire Interface Easy to integrate with microcontrollers using a voltage divider circuit
Wide operating voltage up to 12Vp-p, with resonating frequency typically 1.3kHz to 4.6kHz depending on model
Use with Arduino Tone library for generating beeps and melodies
Requires an external oscillating circuit to produce sound does not selfoscillate like a buzzer
