@kasra ,

You can use QSerialPort class to receive data.

Qt Documentation : QSerialPort Class

When the serial port receives new data, the signal readyRead() is emitted it.
I think that if it binding to QML. you can handle this data at a circular gauge in qt qml.

Please also refer to QSerialPort sample.
