SW420 Vibration Sensor

• The SW420 Vibration Sensor Module is designed to detect mechanical vibration, movement, shocks, or sudden impacts.
• It uses a spring-based mechanical vibration switch (SW-420) that triggers when physical vibration or movement is sensed.
• The module includes an LM393 comparator IC, which converts the vibration signal into a digital output:
  • HIGH → Vibration detected
  • LOW → No vibration
• An onboard potentiometer allows precise sensitivity adjustment, enabling the sensor to respond to different vibration levels.
• Simple, low-cost, and ideal for Arduino, Raspberry Pi, and other microcontroller projects.
• Frequently used in security, robotics, and machine monitoring where vibration detection is essential.
• Easy plug-and-play operation—just power it and read the digital output pin.

PACKAGE INCLUDES:

• 1 × Vibration Sensor Module (SW-420) with LM393 Comparator
