Membuat Kipas Angin Otomatis IoT Dengan ESP32 dan KME Smart TANPA CODING

Introduction

In this tutorial, we will create an automatic fan system using the ESP32 and KME Smart platform without requiring any coding. This project utilizes a DHT11 sensor to monitor environmental parameters and control the fan accordingly. This guide will walk you through the components needed, hardware assembly, configuration, and final testing.

Step 1: Gather Required Components

To start the project, you will need the following components:

• ESP32 Development Board
• DHT11 Temperature and Humidity Sensor
• KME Smart Module
• Fan (DC or AC depending on your setup)
• Power Supply
• Jump Wires
• Breadboard (optional for initial setup)

Practical Tips

• Ensure you have a stable power supply for the ESP32 and the fan.
• Double-check the compatibility of the fan with your power supply.

Step 2: Assemble the Hardware

Follow these steps to assemble your hardware components:

1. Connect the DHT11 Sensor to the ESP32:

   • Connect VCC of DHT11 to 3.3V on ESP32.
   • Connect GND of DHT11 to GND on ESP32.
   • Connect the Data pin of DHT11 to a digital pin on ESP32 (e.g., GPIO 4).

2. Connect the Fan:

   • If using a DC fan, connect the positive terminal to a suitable GPIO pin for control.
   • Connect the negative terminal to the GND.

3. Ensure all connections are secure to prevent disconnections during operation.

Common Pitfalls

• Make sure the DHT11 is connected correctly; incorrect connections can lead to faulty readings.
• Verify that your power supply matches the fan's voltage requirements.

Step 3: Configure KME Smart

Once the hardware is assembled, you will need to configure it using the KME Smart platform:

1. Access KME Smart:

   • Go to the KME Smart website (https://www.kmesmart.com/).

2. Create a New Project:

   • Log in or create an account if you do not have one.
   • Start a new project and select the ESP32 as your device.

3. Set Up Sensor Parameters:

   • Configure the DHT11 sensor inputs for temperature and humidity.
   • Define the thresholds for fan operation (e.g., turn on if temperature exceeds 30°C).

4. Set Up Output Controls:

   • Assign the GPIO pin connected to the fan as an output.
   • Create rules to control the fan based on the DHT11 readings.

Practical Tips

• Use the KME Smart documentation for guidance on setting parameters.
• Test different thresholds to find the optimal settings for your environment.

Step 4: Test the System

After configuration, it's time to test your automatic fan system:

1. Power On the System:

   • Ensure that all components are connected and powered correctly.

2. Monitor the Readings:

   • Check the KME Smart dashboard for real-time temperature and humidity readings from the DHT11 sensor.

3. Test Fan Operation:

   • Manipulate the environment (e.g., heat the area) to see if the fan activates according to your set parameters.
   • Adjust thresholds if necessary based on performance.

Common Pitfalls

• If the fan does not operate, double-check the wiring and KME Smart configuration.
• Ensure that the ESP32 is connected to the internet for KME Smart to function.

Conclusion

You have successfully created an automatic fan system using the ESP32 and KME Smart without coding. This project not only enhances your understanding of IoT but also improves home automation efficiency. As next steps, consider experimenting with additional sensors or expanding your project with more smart devices. Enjoy your new automated setup!
