Ceramic Piezo Vibration Sensor Disc (Piezoelectric Shock & Vibration Detection Sensor)

The Ceramic Piezo Vibration Sensor Disc is a passive piezoelectric sensing element designed to detect vibration, shock, impact, bending, and mechanical stress by generating an electrical voltage. Manufactured using piezoelectric ceramic material bonded to a metal substrate, the sensor converts mechanical energy directly into analog electrical signals without requiring an external power supply. It is widely used in vibration monitoring, knock detection, impact sensing, security systems, musical instruments, energy harvesting, and embedded electronics projects. The sensor can be interfaced with Arduino, ESP32, STM32, Raspberry Pi (with ADC), and other microcontrollers using analog input or signal conditioning circuits.
