Piezoelectric Knock Vibration Sensor Switch Module

The Piezoelectric Knock Vibration Sensor Switch Module is a versatile sensor designed to detect vibration, shock, or impact with high sensitivity. It provides both digital (TTL) and analog outputs, allowing easy integration into microcontroller-based projects such as Arduino, ESP32, or Raspberry Pi.

With adjustable sensitivity via a built-in potentiometer, this module can detect anything from a light tap to a strong impact. An onboard LED indicator provides visual feedback whenever a vibration is detected, making it ideal for motion-activated systems, security devices, and interactive electronics.

Compact and easy to use, this sensor module is perfect for DIY electronics, automation projects, and vibration detection systems.

Key Features

• Dual Output Mode:

  • Digital Output (TTL): High/low signal for triggering events.

  • Analog Output: Variable voltage output proportional to vibration intensity.

• Adjustable Sensitivity:
  Fine-tune detection level using the onboard potentiometer.
