The SW-420 Vibration Sensor Module is a simple electronic sensor designed to detect vibration, shock and movement. It is commonly used in Arduino projects, alarm systems and automation applications.
When vibration reaches the selected sensitivity level, the module provides a digital output signal that can be read by a microcontroller such as an Arduino or ESP32.

SW-420 Pin Connection
The module normally includes three main connections:
🔴 VCC — Connect to the power supply.
⚫ GND — Connect to ground.
🔵 DO (Digital Output) — Connect to a digital input pin on your Arduino, ESP32 or other microcontroller.
Adjusting the Sensitivity
The SW-420 module includes an onboard potentiometer that allows you to adjust its sensitivity.
By turning the potentiometer, you can change the vibration level required to trigger the sensor output.
Common Applications
The SW-420 Vibration Sensor can be used for:
Alarm and security systems
Vibration monitoring
Shock and impact detection
Arduino projects
ESP32 projects
DIY automation systems
