Adjustable Sensitivity Vibration Sensor Switch Module – High Precision with Delay Control

Description

Description

The Adjustable Sensitivity Vibration Sensor Switch Module – High Precision with Delay Control is a sophisticated, intelligent vibration detection and control device designed for industrial equipment protection, security systems, and automation applications. This advanced module combines a highly sensitive piezoelectric or spring-based vibration sensor with a built-in relay, adjustable sensitivity threshold, and programmable delay timer – all in a compact, easy-to-use package.

What sets this module apart from basic vibration sensors is its dual adjustment capability. First, the onboard potentiometer allows you to fine-tune the sensitivity from light touch detection to heavy impact only, ensuring you can dial in exactly the response your application requires. Second, the independent delay control circuit lets you set how long the relay remains activated after vibration stops – from as short as 1 second up to 240 seconds or more, depending on the model .

The module operates on 5V or 12V DC (selectable by model) and features a built-in SPDT relay rated for 10A at 250V AC or 30V DC, capable of controlling fans, alarms, motors, lights, or shutting down equipment directly. An LED indicator provides clear visual confirmation of relay status, and the module can be configured for either latching or non-latching operation.

Whether you need to trigger an alarm when a safe is tampered with, shut down a washing machine when it becomes unbalanced, detect conveyor belt jams, protect industrial pumps from excessive vibration, or create a smart anti-theft system for vehicles or equipment, this adjustable sensitivity vibration switch module delivers precision control in a plug-and-play format – no microcontroller programming required.

Key Features

• Dual Adjustable Parameters – Independent sensitivity adjustment (via potentiometer) and delay time adjustment (via potentiometer or digital buttons) for complete application customization .

• Wide Delay Time Range – Adjustable delay from 1 second to 240 seconds (or up to 999 seconds on advanced models), allowing the relay to stay activated after vibration stops .

• High Sensitivity Detection – Capable of detecting subtle vibrations (as low as 0.5g to 1g threshold) while allowing adjustment to ignore minor noise .

• Built-in SPDT Relay – Controls external devices up to 10A / 250V AC or 10A / 30V DC, suitable for alarms, fans, motors, and equipment shutdown.

• Dual Voltage Options – Available in 5V DC (USB/Arduino compatible) or 12V DC (automotive/industrial standard) configurations.

• Real-Time LED Indicators – Power LED shows module status; relay LED indicates when output is activated.

• Fail-Safe Capable – NC (Normally Closed) output option available for equipment protection applications where power loss should trigger a safe state.

• Standalone Operation – No microcontroller, programming, or software required – works immediately after wiring and adjustment.

• Compact Form Factor – Small footprint (approx. 60mm x 40mm) fits easily into control panels, equipment enclosures, or security housings .

• Low Standby Current – Consumes less than 1mA in standby mode, making it suitable for battery-powered applications .
