SW-420 Vibration Sensor Module – Shock & Movement Detection

The SW-420 Vibration Sensor Module is a reliable and sensitive device used to detect shocks, vibrations, or sudden movements. It is commonly used in security systems, vibration alarms, smart projects, industrial monitoring, and motion-triggered devices.

When vibration is detected, the sensor outputs a digital signal, making it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers. It includes an onboard comparator and adjustable sensitivity using a potentiometer.

Key Features:

• Detects vibration, shock, and sudden motion

• Digital output for easy interfacing

• Adjustable sensitivity (with potentiometer)

• Onboard LM393 comparator for stable performance

• Compatible with Arduino, ESP32, Raspberry Pi

• Useful for vibration alarms, security systems, and smart projects

• Simple, compact, and low-power design
