The ElectroBot SW-420 Vibration/Shock Sensor Module is a compact and reliable sensing solution designed to detect vibration, shock, and impact in robotics, monitoring systems, and embedded electronics projects. This module integrates the popular SW-420 vibration sensor with signal conditioning circuitry, producing a digital HIGH/LOW output that changes state when vibration or shock above the set threshold is detected.

Powered by a standard 3.3V to 5V DC supply, the SW-420 module is easy to integrate with popular development platforms such as Arduino, Raspberry Pi (via digital input), ESP32, AVR, PIC, and ARM microcontrollers. The onboard potentiometer allows you to adjust the sensitivity threshold, giving you control over how responsive the sensor is to motion or impact.

A built-in status LED provides visual feedback when vibration is detected, making setup, testing, and debugging more intuitive. The simple 3-pin interface (VCC, GND, OUT) ensures hassle-free wiring on breadboards, perf boards, or custom PCBs.

This vibration sensor module is widely used in applications such as fall detection systems, collision alerts, smart alarms, robot bump sensing, earthquake/shake detection, industrial machine monitoring, and DIY security projects. Its fast response and adjustable sensitivity make it suitable for both educational prototypes and practical robotics/automation systems.

Whether you’re building a robot that reacts to impact, an alarm that triggers on physical disturbance, or a machine health monitoring system, the ElectroBot SW-420 Vibration/Shock Sensor Module delivers dependable performance and straightforward implementation.
