Piezoelectric Vibration & Shock Sensor Module — Adjustable Sensitivity, TTL Output
This piezoelectric vibration sensor module detects mechanical shock, knock, and vibration using a piezoelectric ceramic element. When vibration is detected, the module outputs a TTL-level digital signal that can be read directly by Arduino, STM32, 51 MCU, or any 5V microcontroller. Sensitivity is adjustable via an onboard potentiometer, making it suitable for a wide range of detection thresholds.
