PIR motion sensor with Neon LED strip

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.

This project focuses on interfacing a PIR (Passive Infrared) motion sensor with a flexible neon LED strip using the EzloPi device. The PIR sensor detects motion in its field of view, and upon sensing movement, it triggers the Neon LED strip to illuminate. The project aims to create an automatic lighting system, where the LED strip responds to real-time motion detection. The EzloPi device’s GPIO pins are used to connect and control the PIR sensor and the LED strip, allowing for an energy-efficient and smart lighting solution.

Welcome to the project demonstration video section. The following video showcases the key aspects of PIR motion sensor with Neon LED strip, providing a visual walkthrough of its implementation.

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

• ESP32 as an EzloPi smart device.
• PIR sensor.
• XY-MOS, high-power dual MOSFET driver module.
• Flexible Neon LED strip.
• 12V Power Supply.

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

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

From ESP32 to PIR Sensor:

From ESP32 to the MOSFET driver module:

From Power Supply to the MOSFET driver module:

From MOSFET driver module to LED Strip:

1. 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 have set it to the PIR Motion Sensor.
• Set INPUT GPIO to 13.
• Set Device Subtype to PIR Sensor.
• Set Resistor to PULL DOWN.
• Then Click Apply Button.

8. In the Device Configuration, tab click on Digital Output.

9. A Digital Output window will open for inputting the following parameters:

• Set a Device name of your choosing. In our case, we set it to the Neon LED.
• Set INPUT GPIO to 12.
• Set Device Subtype to LED.
• Set Resistor to PULL UP.
• 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.

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

11. 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.”

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

13. 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. Now, on the MiOS web dashboard, you will see the tiles of your connected devices as shown above as PIR Motion Sensor and Neon LED.
4. Currently, no motion is detected by the sensor therefore both PIR sensor and LED strip tiles show the ‘’No Motion " and "OFF " message respectively.

MeshBots:

4. On the left 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 EzloPi.

7. On the next screen you will see that we can create a name of our choosing, in this case we write it as Test005.

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 Motion Sensor.
• Set the Capability to Switch.
• Set the value to True.

10. Set these values in the TRUE part of the ACTION section.

• Set Node type to Device.
• Set Controllable to Neon LED.
• Set Capability to switch.
• Set value to true.

11. Set these values in the FALSE part of the ACTION section.

• Set Node type to Device.
• Set Controllable to Neon LED.
• Set Capability to switch.
• Set value to false.
• 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.

14. Now as seen above, it shows that when the PIR Motion sensor gets triggered ON or detects any motion, the Neon LED gets turned ON because of the rules we have set in the meshbot.

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. On the MiOS mobile dashboard, you will see the tiles of your connected devices as shown above as PIR Motion Sensor and Neon LED.
6. Currently, no motion is detected by the sensor therefore both the PIR sensor and LED tiles show the ‘’No Motion " and "OFF " message respectively.

6. Now as seen above, it shows that when the PIR Motion sensor gets triggered ON because of some motion then the Neon LED gets turned ON because of the rules we have set in the meshbot.
