Proximity sensing with Reed Switch

Open doors to endless possibilities with EzloPi!

Proximity sensing with Reed Switch

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

This project demonstrates the interfacing of a reed switch module with the EzloPi device. The primary function of the KY-025 module is to detect the presence or absence of a magnetic field. It is commonly used for proximity sensing. Reed switches consist of two ferrous materials enclosed in a glass envelope. When exposed to a magnetic field, these materials come into contact, completing an electrical circuit.

2. Project Demonstration Video

Welcome to the project demonstration video section. The following video showcases the key aspects of How to create your own smart Reed Switch using EzloPi platform , providing a visual walkthrough of its implementation.

3. Circuit Diagram & Interface

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

  • ESP32 as an EzloPi smart device.
  • KY-025 Reed Switch module.

The wiring diagram of ESP32 is represented as follows:

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

From ESP32 to the KY-025 Reed Switch module:

  • Connect the VCC of the ESP32 with the VCC of the KY-025 module.
  • Connect the GND pin of the ESP32 to the GND pin of the KY-025 module.
  • Connect the ESP32 GPIO D4 to the D0 of the KY-025 module.

4. Interfacing the Reed Switch module using the EzloPi Web Flasher:

1. Set up your device/hardware by visiting config.ezlopi.com

  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 Digital Input.
  1. An Digital Input window will open for inputting the following parameters:
  • Set a device name of your choosing. In our case, we set it to Reed Switch
  • Set device Subtype to Reed Switch.
  • Set the ADC input pin to 4.
  • Now Click the 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.

5. 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 MiOS mobile dashboard, you will be able to see the tile of your connected device.
  2. As you can see in the example given above, we can see the Reed Switch module tile. It shows a “Closed” message on the tile as the sensor is not detecting any magnetic field.
  1. Similarly, It shows an “Open” message on the tile when the sensor detects magnetic fields.

6. MiOS Web Application

  1. After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com
  1. Use the same credentials to log in that you used for configuring the controller with the web flasher.
  1. As you can see in the MiOS web dashboard, we can see two rain sensor tiles. One tile shows a “Leak detected” message on the tile for when the sensor is detecting any raindrops or rain water, meanwhile the other tile is showing a “No Leak” message on the tile as the sensor is not detecting any raindrops or rain water.
  1. As you can see in the MiOS web dashboard, we can see two rain sensor tiles. One tile shows a “Leak detected” message on the tile for when the sensor is detecting any raindrops or rain water, meanwhile the other tile is showing a “No Leak” message on the tile as the sensor is not detecting any raindrops or rain water.
