Motion sensing using SparkFun OpenPIR SEN-13968

Chase Flash (two LEDs flash in secondary color while the rest is lit in primary. The flashing LEDs wander from start to end) effect implementation by interfacing the addressable LED with the EzloPi device.

The following project aims to integrate the SparkFun OpenPIR SEN-13968 sensor, designed for motion detection, with the EzloPi device. The EzloPi device is a versatile home automation controller, providing a centralized platform for managing various smart home devices. By interfacing the OpenPIR sensor with the EzloPi device, users can enhance their home security and automation capabilities. This integration enables real-time monitoring of motion events detected by the OpenPIR sensor through the MiOS interface. Users can customize actions and triggers based on motion events, such as activating lights, sending alerts, etc. provides a seamless and effective solution to users for motion sensing for a smart home environment.

Welcome to the project demonstration video section. The following video showcases the key aspects of Motion sensing using SparkFun OpenPIR SEN-13968, providing a visual walkthrough of its implementation.

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

• ESP32 as an EzloPi smart device.
• SparkFun OpenPIR SEN-13968.

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 SparkFun OpenPIR SEN-13968:

1. First setup your MiOS account by visiting Setup MiOS Account and 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. Click on the Configure Wifi button. 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 Mini PIR motion Sensor.
• Set OUT GPIO to 4.
• Set Device subtype to PIR Sensor.
• Then Click Apply Button.
• 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.

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

9. 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.”

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

11. After some time, a popup will appear on the bottom right hand side of your screen saying Device Flashed Successfully!. This means that your device has been set up successfully.

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. As you can see in the MiOS mobile app dashboard, we can see the motion sensor tile. The above figure indicates that motion is being detected by the sensor.

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

2. Use the same credentials 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 above, we can see the motion sensor tile. The above figure indicates that motion is being detected by the sensor.

4. When no motion is detected by the sensor, the MiOS web dashboard tile will show the status “No motion” as demonstrated above.
