The SW-520D Tilt & Vibration Sensor Module is a comparator-based breakout board built around the SW-520D ball switch, giving projects a simple way to detect tilting, shaking, or orientation changes. An onboard LM393 comparator and sensitivity trimmer clean up the raw switch signal into a stable digital output.
Key features:
- SW-520D Ball Switch: A rolling-ball metal switch that opens or closes the circuit as the module is tilted or shaken.
- LM393 Comparator: Converts the raw switch signal into a clean digital HIGH/LOW output for reliable microcontroller reads.
- Adjustable Sensitivity: An onboard potentiometer sets the trigger threshold to match the application.
- Dual Status LEDs: Power and signal indicator LEDs make bench testing and debugging quick and visual.
- Wide Supply Range: Runs from 3.3V to 5V, compatible with common Arduino and ESP-series boards.
- 3-Pin Digital Output: A simple VCC, GND, and DO header keeps wiring straightforward.
It suits tilt alarms, tip-over detection, shake-activated triggers, and simple orientation sensing in robotics and security projects.
