Review of KEYESTUDIO ESP32 Smart Home Starter Kit

If you are looking for a fun and educational way to learn about electronics and programming, you might want to check out the KEYESTUDIO ESP32 Smart Home Starter Kit. This kit comes with a wooden house model, an ESP32 development board, and various sensors and modules that allow you to create different smart home features. You can also control the devices with your smartphone via Bluetooth or Wi-Fi. In this review, I will go over the main features, pros and cons, and my personal experience with this kit.

What’s in the box?

The kit includes the following components:

  • A wooden house model with pre-drilled holes and screws for easy assembly.
  • An ESP32 development board with a micro USB cable for power and programming.
  • A PIR motion sensor that detects movement and triggers an LED module.
  • A gas sensor that detects hazardous gases such as methane and carbon monoxide and triggers a buzzer alarm.
  • A temperature and humidity sensor that measures the environmental conditions and displays them on an LCD screen.
  • A 4-digit display that shows the house password for opening the door.
  • A servo motor that controls the door lock.
  • A DC motor that controls the window opening and closing.
  • A potentiometer that adjusts the speed of the DC motor.
  • A relay module that switches the power supply for the DC motor.
  • A button module that controls the relay module.
  • A sound sensor that detects sound levels and triggers a Morse code LED.
  • A breadboard and jumper wires for connecting the components.
  • A battery holder and 6 AA batteries for powering the house model.

The kit also comes with online tutorials that provide step-by-step instructions on how to assemble the house model, connect the components, and program the ESP32 board. The tutorials are available in two programming languages: C and MicroPython. You can choose the one that suits your preference and skill level.

What can you do with the kit?

The kit allows you to create different smart home features that simulate real-life scenarios. For example, you can:

  • Set a password for opening the door and use the 4-digit display and the servo motor to lock and unlock the door.
  • Use the PIR motion sensor and the LED module to create a motion-activated light that turns on when someone approaches the door.
  • Use the gas sensor and the buzzer alarm to create a gas leak detector that warns you of dangerous gases in the house.
  • Use the temperature and humidity sensor and the LCD screen to monitor the indoor climate and display the readings.
  • Use the DC motor, the potentiometer, the relay module, and the button module to create a window opener that can be controlled manually or automatically.
  • Use the sound sensor and the Morse code LED to create a sound-activated Morse code transmitter that sends messages with light signals.

You can also control the devices with your smartphone via Bluetooth or Wi-Fi. You can use the Blynk app or the WebREPL app to connect to the ESP32 board and send commands or receive data. For example, you can:

  • Open or close the door remotely with your phone.
  • Turn on or off the LED light with your phone.
  • Get notified of gas leaks or high temperature and humidity levels on your phone.
  • Adjust the window opening and closing speed with your phone.
  • Send or receive Morse code messages with your phone.

The kit also allows you to explore the possibilities of the ESP32 board, which is a powerful and versatile microcontroller that supports various communication protocols, sensors, and modules. You can use the ESP32 board for other projects and applications, such as robotics, IoT, web servers, etc.

What are the pros and cons of the kit?

Here are some of the pros and cons of the kit that I found:

Pros

  • The kit is easy to assemble and use. The wooden house model is well-designed and sturdy, and the components are clearly labeled and color-coded. The online tutorials are detailed and clear, and provide code examples and troubleshooting tips.
  • The kit is fun and educational. The kit provides a hands-on and interactive way to learn about electronics and programming, and stimulates creativity and problem-solving skills. The kit also introduces the concepts and applications of smart home and IoT, which are relevant and useful in today’s world.
  • The kit is versatile and expandable. The kit offers multiple features and functions that can be customized and combined. The kit also supports various sensors and modules that can be added to the house model or the ESP32 board. The kit can be used for different projects and purposes, depending on your interest and skill level.

Cons

  • The kit requires some basic knowledge and skills. The kit is not suitable for absolute beginners who have no prior experience with electronics and programming. The kit requires some familiarity with the ESP32 board, the Arduino IDE or the MicroPython editor, the Blynk app or the WebREPL app, and the C or MicroPython language.
  • The kit has some limitations and issues. The kit does not include a printed manual or a storage case, which would be helpful and convenient. The kit also has some minor flaws and bugs, such as the LCD screen being too small, the gas sensor being too sensitive, the Morse code LED being too dim, etc.

What is my personal experience with the kit?

I bought the kit as a gift for my nephew, who is 15 years old and interested in electronics and programming. We assembled the kit together and followed the online tutorials to program the ESP32 board. We had a lot of fun and learned a lot from the kit. We enjoyed creating different smart home features and controlling them with our phones. We also experimented with different sensors and modules and added them to the house model. We made a light sensor that adjusts the brightness of the LED light, a soil moisture sensor that waters the plants, a camera module that takes photos, etc. We also tried to use the ESP32 board for other projects, such as making a robot car, a web server, a weather station, etc. The kit was a great way to spend quality time and learn new things.

Conclusion

The KEYESTUDIO ESP32 Smart Home Starter Kit is a great kit for anyone who wants to learn about electronics and programming in a fun and practical way. The kit provides a wooden house model, an ESP32 development board, and various sensors and modules that allow you to create different smart home features and control them with your smartphone. The kit also allows you to explore the possibilities of the ESP32 board, which is a powerful and versatile microcontroller that supports various communication protocols, sensors, and modules. The kit is easy to assemble and use, fun and educational, versatile and expandable, but it also requires some basic knowledge and skills, and has some limitations and issues. I would recommend this kit to anyone who is looking for a creative and thoughtful gift for aspiring engineers and children, or anyone who wants to have fun and learn new things.
