Tilt Sensor Vibration Alarm Vibration Switch Module for Arduino
📳 Tilt Sensor Vibration Alarm / Vibration Switch Module
📌 Overview
The Tilt Sensor Vibration Switch Module is a compact module used to detect vibration, movement, or tilt and generate a digital trigger signal.
👉 Commonly used in:
🚨 Anti-theft alarm systems
🤖 Motion detection projects
🧳 Luggage/security alarms
📦 Vibration monitoring
🧠 Working Principle
The module contains a vibration/tilt switch (spring or ball type):
At rest → no contact → no signal
When shaken/tilted → internal contact touches → signal generated
👉 Works based on mechanical movement and switching
Often paired with a comparator (like LM393) for stable output
