Features:

• Dual Output Types: Offers both TTL level output (high/low) for triggering events and an analog output based on vibration intensity.
• Adjustable Sensitivity: Sensitivity is adjustable using a potentiometer, allowing fine-tuning for different applications (e.g., responding to a light tap or a stronger knock).
• LED Indication: Includes an LED to indicate when the sensor is activated.
• Control Output: TTL output can control currents up to 1A, making it suitable for driving high-power LEDs or other devices.
• Compact Design: Ideal for integrating into projects requiring vibration or knock detection.

The Piezoelectric Knock Vibration Sensor Module is an advanced sensor designed to detect vibrations, knocks, and impacts. It features both digital and analog output signals, providing versatility in various applications. With adjustable sensitivity, this module can respond to different vibration intensities, such as tapping with your hand or even blowing air on it. It also includes an LED indicator for easy visual feedback of the sensor's state.
