# Ethernet-Connected Vibration Sensor Project with SW-Series and WIZnet Module

## Question

Asked by owen000821 on 2025-09-04 in IO Modules.

Hello Makers! 👋

I’m working on a simple yet powerful project that combines the [**SW-Series vibration sensor**](https://easyelecmodule.com/sw-series-vibration-sensor/)** (like SW-420)** with a **WIZnet Ethernet module** to build a real-time vibration monitoring system.

#### Components Used

**SW-Series Vibration Sensor (SW-420):**

Detects vibrations using a spring-based mechanism

Adjustable sensitivity via onboard potentiometer

Digital HIGH/LOW output for easy interfacing

Operates on 3.3V or 5V logic

**WIZnet Ethernet Module (e.g., WIZ550web):**

Built-in web server for I/O monitoring and control

Supports digital/analog data via HTTP GET/POST calls

Custom web pages can be stored in onboard memory or microSD

#### Project Concept

**Connect the sensor:** Hook up VCC, GND, and digital output (DO) from the SW-420 to a digital input pin on the WIZnet module.

**Configure I/O monitoring:** Use the module’s web interface to read sensor state (HIGH/LOW) over Ethernet.

**Trigger actions:** When vibration is detected, the module can update a web dashboard, log an event, or trigger an alarm.

**Remote access:** The sensor status is accessible through a simple web page hosted directly on the WIZnet module.

#### Example Use Case

Place the vibration sensor on a machine to monitor unusual activity.

Connect the WIZnet module to your network.

Open the hosted web page to check vibration status in real time.

Optional: Extend with notifications, data logging, or multi-sensor support.

#### Why This Project is Interesting

**Low-cost & simple**: SW-420 is easy to use and inexpensive.

**Web-enabled monitoring**: Access data remotely via Ethernet.

**Customizable interface**: Build your own dashboard with HTML/JS.

**Scalable**: Add multiple sensors for wider monitoring coverage.

#### Questions for the Community

What’s the best way to handle debounce or false triggers with vibration sensors?

Has anyone tried long-term vibration data logging with WIZnet modules?

How would you extend this project to support multiple sensors at once?

Looking forward to your thoughts and ideas!
