Overview

The SW-420 NC Vibration Sensor is a high-sensitivity vibration detection module designed to detect sudden movements, shocks, or vibrations in various applications. It features a Normally Closed (NC) vibration switch that triggers when subjected to motion, making it ideal for security systems, anti-theft devices, vehicle monitoring, and DIY electronics projects.

This sensor is compact, easy to integrate, and works well with microcontrollers like Arduino, ESP8266, ESP32, and Raspberry Pi, providing a reliable way to monitor mechanical disturbances.

Description

Key Features:

Vibration Detection: Sensitive to shocks, vibrations, and movements.
Normally Closed (NC) Output: Conducts when stable, opens circuit upon vibration.
Adjustable Sensitivity: Built-in potentiometer for tuning detection threshold.
Digital & Analog Output: Compatible with microcontrollers (Arduino, ESP, Raspberry Pi).
Wide Voltage Range: Operates at 3.3V–5V DC, suitable for most embedded systems.
Compact & Durable: Encased in a sturdy module with mounting holes.
Low Power Consumption: Ideal for battery-powered projects.

Applications:

Security Alarms (Anti-theft, door/window sensors)
Vehicle Impact Detection (Car/truck vibration monitoring)
Industrial Equipment Monitoring (Machinery fault detection)
DIY Electronics & IoT Projects
Earthquake/Tilt Sensing (Basic motion detection)
