Good value, needs calibration

Works well once you adjust the sensitivity dial. Out of the box, it was a bit too twitchy, but after tweaking, it ignores wind but catches actual tampering.

Compact and reliable

Small enough to hide easily on the frame. I've had it installed for three months through rain and sun, and it hasn't failed once.

Great replacement part

My old vibration sensor died, and this was a perfect direct replacement. The response time is instant, triggering the siren immediately upon impact.

Solid construction

The ceramic plate feels durable. I mounted it with strong adhesive tape, and it holds up well against engine vibrations without false alarms.

Decent but instructions are vague

The hardware itself seems solid, but the wiring diagram provided was very basic. Had to look up online tutorials to get the polarity right.

Perfect for my custom alarm build

This sensor is incredibly sensitive and easy to wire into my existing motorcycle alarm system. The ceramic plate picks up even slight bumps, giving me peace of mind when parking downtown.

5 FAQ

Q: Can this sensor work with a 24V truck electrical system?

A: This specific module is designed for 12V systems typically found in motorcycles. Using it directly on 24V may damage the component; a voltage regulator would be required.

Q: Does this come with mounting screws?

A: No, the package includes only the sensor module and wires. We recommend using high-strength double-sided adhesive or zip ties for mounting depending on your bike's frame.

Q: Is this sensor waterproof for outdoor mounting?

A: The module has a water-resistant coating suitable for general outdoor use, but we recommend sealing the connection points with electrical tape or heat shrink tubing for full protection.

Q: How do I adjust the sensitivity level?

A: There is a small blue potentiometer screw on the circuit board. Turn it clockwise to increase sensitivity and counter-clockwise to decrease it.

Q: What is the maximum current this sensor can handle?

A: This is a signal sensor, not a relay. It outputs a low-voltage signal to trigger your main alarm unit and should not be used to power high-current devices directly.
