VIBRATION SENSOR SW520

Tilt and Vibration Sensor Module using the SW-520D ball-rolling tilt switch (not mercury type). Output LOW when not tilted past threshold; HIGH when tilted beyond it (~45°–130° depending on angular velocity). Power LED and status LED for visual indication. M3 mounting hole. Compatible with Arduino, 8051, PIC, and any 3.3–5V digital MCU. If DO is unresponsive, adjust the onboard potentiometer to centre.

Pin Connection:

• VCC — 5V
• GND — Ground
• DO — Digital output
