Chose One SW-420 Electric Vehicle Alarm Vibration Sensor and Horn: Normally closed vibration sensor
For the DIY electric vehicle owner who wants to add a simple, reliable vibration alarm, this SW-420 sensor is your go-to solution. It's perfect for detecting bumps or tampering on your e-bike, scooter, or small EV, giving you peace of mind when parked in public spaces.
Unlike complex security systems, this sensor offers a straightforward normally closed setup that triggers an alarm horn with minimal wiring. The on-board LM393 comparator lets you adjust sensitivity easily, so you can fine-tune it to ignore minor vibrations while catching real threats. Install it with the fixed bolt-hole for a secure fit, and enjoy quick conductive response in about 2ms for instant alerts.
