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.

Function: Detect tilt Voltage: 3.3V 5V Output: Digital (HIGH/LOW) Detection: Angle change Type: Ball / Mercury Response: On/Off switch
Pin Configuration (Typical Module)
Tilt Sensor VCC Power (3.3V/5V) GND Ground DO Digital Output
Working Logic
Position | Output |
Upright | LOW / HIGH (depends on module) |
Tilted | HIGH / LOW (opposite state) |
Works like a simple switch Some modules include a comparator (LM393) for stable output
