A Python-based GUI application for recording and visualizing live data from the JUMO Midas pressure sensor.
To run the software on your PC, ensure you have the following installed:
- Python (version 3.7 or later recommended)
- The following Python packages:
PyQt5pyserialpyqtgraph
You can install them using pip:
pip install PyQt5 pyserial pyqtgraphClick the Code button at the top right of the repository page, then select Download ZIP. Extract the contents to a location on your computer.
- Open the extracted folder in Visual Studio Code or your preferred IDE.
- Run the
main.pyfile inside the src folder.
If everything is set up correctly and the required packages are installed, the GUI should launch and appear as shown in the screenshot above.
The software provides an intuitive interface for interacting with the JUMO Midas pressure sensor. Here's a brief overview of its core functionalities:
-
Device Selection:
Use the dropdown menu to select the appropriate serial device connected to your sensor. -
Live Data Visualization:
The "Live View" section displays a real-time graph of the latest 50 data points, allowing you to monitor sensor output dynamically. -
Data Logging:
In the "Data Recording" section, you can save recorded data to a CSV file for further analysis or archival purposes. -
Logs Section:
Displays system messages and error logs to help with troubleshooting and understanding the software’s status. -
COM Input (Debug Only):
This section is intended for debugging and internal use. It does not play a role in regular operation.
To upload the firmware to your Arduino board, follow the steps below.
- Open VSCode and click the PlatformIO icon (a small alien head on the left sidebar).
- Select "Open Project" and choose the Arduino source code folder from this repository.
- PlatformIO will automatically initialize the project. Once it's ready, you'll see options like "Build" and "Upload" at the top of the window.
- Click "Upload" to compile and flash the code onto your connected Arduino board.
- This project uses the Arduino's analog input pins A0 to A5 to read voltage signals from connected sensors.
- You can connect up to six sensors simultaneously (one per pin from A0 to A5).
The pressure sensors used in this project output a 4–20 mA current signal. Since Arduino analog pins can only read voltage, a conversion circuit is required to translate the 4–20 mA signal into a voltage range the Arduino can interpret.
