### ❤️‍🩹 Known Issues
53+
To build the **Windy** device, you will need the following components:
4854

49-
Unfortunately, not all features we intended to implement function correctly.
50-
We list here all known issues:
51-
- The device collects data only while it is connected to the phone.
52-
- The application experiences connection issues in everyday use, especially when the application is killed and the device is powered off and on in different combinations.
55+
- **ESP32 Microcontroller**: This will be the brain of your device.
56+
- **Air Quality Sensor**: Choose a sensor that meets your needs (e.g., MQ-135).
57+
- **Power Supply**: Ensure you have a reliable power source.
58+
- **3D Printed Case**: You can find the design files in the `3D-Print` folder.

86-
Make sure to have flutter installed as well as suitable platform for testing.
87-
Use the official page in case you need it [flutter](https://github.com/flutter).
87+
To create the housing for your **Windy** device, you will need to 3D print the case. The STL files are located in the `3D-Print` folder.

## 👷🏻 Building the device
90-
91-
To build the prototype, we welded some commercial components onto a custom PCB board that we designed to enhance ease of assembly and overall elegance. **The PCB project files are included in the PCB folder.** To design the board, we used [KiCad](https://www.kicad.org). A custom 3D-printed shell protects the system, providing durability and aesthetic appeal. **We publish the STL file in the media folder.**
