KY‑002 — Vibration, shock sensor

• Principle of operation: inside is installed a metal twisted spring contact SW‐18015P, which, when shocked or hit, closes the chain, locking to the ground

  Supply voltage: 3.3–5V (e.g. 5V is recommended) .

  Board dimensions: ~18.5×15mm

  Output: digital (HIGH/LOW) – when vibrating outputs LOW (when pull-up is active) or HIGH, depending on the circuit.

  Ideal for simple tasks: door knock detector, vibration monitoring on cars, DIY toys and interactive projects.
