Adjustable Vibration Sensor Relay Module

Turn a vibration event into a switching input for a small electronics project. This 12V board combines a vibration sensor with an adjustable relay response.

✅ Set how readily the board reacts - Sensitivity adjustment lets you tune the response during project testing.

✅ Choose the response interval - Delay adjustment provides another control over the relay behaviour.

✅ Use a contact output for a matched circuit - The relay gives a separate switching interface for an appropriately specified load.

Tune the Event Before Connecting the Load

A vibration-triggered project works best when tested at its actual mounting point. Begin with the sensor and output indication, adjust the settings and verify repeatability before linking the controlled equipment.

The board is not a complete security system, and no radio function is confirmed. Verify the actual contact ratings and wiring rather than treating a relay label as a guarantee for every load. Supply, enclosure and protection are separate.
