Interfacing vibration sensor with esp32

Feel the Beat: EzloPi smart device Dances with Vibration Sensor Brilliance.

Interfacing vibration sensor with esp32

The EzloPi smart devices provide automation through simple, customizable use with our open-source EzloPi platform, making daily life easier and improving human-machine interactions.

Before moving into this example, it is very important to know about the device registration, provisioning and converting the ESP32 device into an EzloPi device along with knowledge of Web Flasher, MiOS Mobile Application for Android/iOS and the MiOS Web Application.

1. About this example

Here we will be interfacing a Vibration Sensor with the EzloPi Smart Device. By integrating a high-performance vibration sensor with EzloPi, we bring you a solution that not only detects subtle movements but also empowers your smart environment with real-time responsiveness.

EzloPi’s meticulously crafted interface ensures that every vibration is translated into actionable data, providing a new dimension to home automation. Whether you seek enhanced security or wish to create interactive scenarios triggered by motion.

Explore the synergy of technology and intelligence as the EzloPi smart device effortlessly interprets vibrations, transforming your space into a dynamic, responsive environment. EzloPi smart device turns your place into a smart, dynamic hub where every move counts.

2. Project Video Demonstration

Welcome to the project demonstration video section. The following video showcases the key aspects of Create your own smart vibration sensor using EzloPi Platform, providing a visual walkthrough of its implementation.

2. Circuit Setup & Interfacing

The following components are required for interfacing using the EzloPi device:

  • ESP32 as EzloPi smart device.
  • LM393 vibration sensor Module.

The wiring diagram is represented as follows:

The following connections are made in order to complete the circuit setup:

From ESP32 to the Vibration Sensor Module:

  • Connect the 3v3 pin from ESP32 to the VCC terminal on the vibration sensor Module.
  • Connect GND to the GND Pin.
  • Connect D5 from the ESP to the signal (D0) pin.

3. Interfacing the Vibration Sensor Module with EzloPi Web Flasher:

1. Set up your device/hardware by visiting

  1. Log in using the credentials which you just set earlier while signing up.
  1. Now, click on the Connect Device button and a pop-up window will appear.
  1. Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.

Click Connect.

  1. If you are new to this and it's your first time configuring, select Create new Device ID. Enter Wifi SSID and Wifi Password.
  1. In the Device Configuration, tab click on Other.
  1. A Digital Output window will open for inputting the following parameters:
  • A window will open for inputting the following parameters:
  • Set a device name of your choosing. In our case, we set it to MQ7.
  • Set Device subtype to MQ7 CO Gas Sensor.
  • Check the box of GPIO 1.
  • Set OUT GPIO 1 to 33.
  • Then Click Apply Button.
  • After clicking the apply button you can see a table of your setting in the device configuration tab.
  • Press the Flash Device button.
  1. A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”
  1. Hold the BOOT button down until the next window appears on the bottom right side of the screen which says “Installation prepared. Please release the boot button now.”
  1. Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.
  1. After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.

4. MiOS App

You can download the MIOS Android app from the Google Play Store and Apple App Store.

Google PlayApple App Store

  1. After downloading the app, proceed to install the application and open it.
  1. Using the MIOS mobile application, create a new Ezlo Cloud account using the sign-up option. If you already have an account, you may proceed to log in.
  1. After successfully logging in, you will be able to see the number of controllers connected such as a lamp, fan, or any other device in the MiOS app. Tap on any controller of your desired ID:
  1. You will be able to see the status of your controller whether it is online or offline. Access the device dashboard, and tap the device. The following view of the dashboard will appear:
  1. After opening the dashboard, you will be able to see the tile of your connected device.
  2. Here, as you can see in the MiOS mobile app dashboard, the vibration sensor tile, which shows the NO Motion.
  1. Similarly, when it detects the vibration, “Motion” is appeared on the tile.

5. MiOS Web Application

  1. After configuring the controller with the EzloPi web flasher, head to
  1. Use the same credentials to log in that you used for configuring the controller with the web flasher.
  1. In the dashboard, you can also see the tile labeled as vibration sensor, which is showing No motion on the tile.
  1. Similarly, when it detects the vibration, “Motion” appears on the tile.
