ESP32 WEMOS D1 R32 and DHT11 Temperature & Humidity Sensor (Replace Arduino board with ESP-based Arduino board)

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

• ESP32 WEMOS D1 R32 as an EzloPi smart device.
• DHT11 Temperature & Humidity Sensor.

The wiring diagram for ESP32 WEMOS D1 R32 is represented as follows:

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

From ESP32 WEMOS D1 R32 to DHT11 Sensor:

• Connect 3V3 from the ESP32 WEMOS D1 R32 to the VCC of the sensor.
• Connect GND from the ESP32 WEMOS D1 R32 to the GND pin of the sensor.
• Connect IO4 from the ESP32 WEMOS D1 R32 to the DATA pin of the sensor.

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 One Wire.

7. A One Wire window will open for inputting the following parameters:

• Set a device name of your choosing. In our case, we set it to DHT11.
• Set OUT GPIO to 4.
• Set Device subtype to DHT11 Temperature Humidity Sensor.
• 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 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:

6. Here, as you can see in the MiOS mobile app, two DHT11 tiles are being displayed. The upper box in the second tile shows the temperature being detected by the sensor and the lower box in that same tile shows the humidity levels being detected by the sensor. Additionally, we can also view the humidity value in a separate tile as well.
7. Here, it can be seen that we have successfully converted an Arduino project into a smart project by using an ESP-based development board.

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. As displayed above in the web dashboard, two DHT11 tiles are displayed. The upper box in the second tile shows the temperature being detected by the sensor and the lower box in that same tile shows the humidity levels being detected by the sensor. Additionally, we can also view the humidity value in a separate tile as well.
4. Here, it can be seen that we have successfully converted an Arduino project into a smart project by using an ESP-based development board.
