Tilt Sensor Module

🔄 Tilt Sensor Module – Complete Guide with Infographic
📌 Overview
A Tilt Sensor Module is a simple electronic device that detects orientation or inclination. It tells whether an object is tilted or upright by opening or closing an internal contact.
🧠 How It Works
Inside the module, there is usually a metal ball or mercury switch:
⚪ Ball Type (common & safe)
When tilted, the metal ball rolls and completes or breaks the circuit.
💧 Mercury Type (less common, toxic)
Mercury flows to connect contacts when tilted.
👉 Output changes depending on the angle of the sensor.
