Motion Detection Alerts using mini PIR sensor & EzloPi meshbot

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.

In this example, a mini PIR motion sensor is interfaced with the EzloPi device. This sensor provides a convenient solution for detecting motion using infrared rays.

With a smaller size factor, the HC-SR505 sensor is comparable to the HC-SR501. It is used as a motion detection sensor and is commonly used in security systems, home automation, and other applications. When interfaced with an EzloPi device, this sensor will enhance your smart home experience. Real time updates for any motion detected can also be monitored via the MiOS app remotely on a smartphone or desktop. With the EzloPi automation meshbots, users can assign tasks or actions to certain rules and conditions to automate various functions such as turning on a fan or light when the sensor detects motion, etc.

Welcome to the project demonstration video section. The following video showcases the key aspects of How to create motion alert via Meshbots easily using mini PIR sensor on EzloPi Platform, providing a visual walkthrough of its implementation.

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

• ESP32 as an EzloPi smart device.
• HC-SR505 Mini PIR motion sensor.

The wiring diagram for ESP32 30 pin is represented as follows:

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

From ESP32 to PIR motion sensor (HC-SR505):

• Connect 3V3 from the ESP32 to the VCC of the sensor.
• Connect GND from the ESP32 to the GND pin of the sensor.
• Connect D5 from the ESP32 to the DATA pin of the sensor.

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

2. Log in using the credentials which you just set earlier while signing up.

3. Now, click on the Connect Device button and a pop-up window will appear.

4. Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.

Click Connect.

5. If you are new to this and it's your first time configuring, select Create new Device ID. Enter Wifi SSID and Wifi Password.
6. In the Device Configuration, tab click on Digital Input.

7. A Digital Input window will open for inputting the following parameters:

• Set a device name of your choosing. In our case, we set it to PIR Sensor.
• Set OUT GPIO to 5.
• Set Device subtype to PIR Sensor.
• 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.

11. A window will appear on the bottom right side of the screen displaying “Please press BOOT button while flashing begins.”

12. 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.”

13. Release the BOOT button from your ESP32 when this pop-up on the bottom right window appears.

14. After some time, a popup will appear saying Device Flashed Successfully! This means that your device has been set up successfully.

1. After configuring the controller with the EzloPi web flasher, head to ezlogic.mios.com

2. Use the same credential to log in that you used for configuring the controller with the web flasher.

3. Here, as you can see in the MiOS web dashboard, we can see the motion sensor tile. The above figure is indicating that motion is not being detected by the sensor.

MeshBots:

4. On the right side of the screen under Automation, click on MeshBots.

5. On meshbot screen, click on Create new MeshBot button present on the top right corner of the screen.

6. After clicking on Create new MeshBot you will see this now under Automation MeshBot click on Cloud.

7. On the next screen you will see that we can create a name of our choosing, in this case we write it as Test003.

8. In the trigger tab you can set the TRIGGER for your device and in the ACTION tab you can set the action to be performed based on the trigger which you have created.

9. Set these things in TRIGGER section:

• Set Node Type to Device.
• Set the Node to PIR sensor.
• Set the Capability to Motion.
• Set the Value to True.

10. Set these values in the ACTION section.

• Set Controllable Type to Notification.
• Set the User to Your user account but in our case the user account is Tayyab.
• Set the Channels to email,push.
• Set the Subject to Motion Update.
• Set the Message body info to Motion is detected.
• After clicking the apply button you can see a table of your setting in the Current configuration tab.

12. After clicking the save button you can see this screen on the top right corner of the screen.

13. Here you can see your saved MeshBot. Now click on Dashboard.

15. The above figure is indicating that motion is being detected by the sensor. Therefore it automatically generates the email to notify the user.

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

1. After downloading the app, proceed to install the application and open it.

2. 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.

3. 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:

4. 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:

5. Here, as you can see in the MiOS mobile app, we can see the motion sensor tile. The above figure is indicating that motion is not being detected by the sensor.

6. The above figure is indicating that motion is being detected by the sensor. Therefore it automatically generates the email to notify the user.
