PytonDAQ - A Python based measurement data acquisition and processing software

This paper introduces PythonDAQ, an open-source Python package for measurement data acquisition, visualization, storage, and post-processing. The code is capable of acquiring measurement data from any sensor with digital data output, performs online calculations, and stores the measured and computed data. A client for live data visualization and tools for postprocessing are also contained in the software package. First, the code is introduced explaining the software architecture and the currently implemented features. Then, the usability is demonstrated by an application at the low-speed compressor test rig FRANCC. As last step, comparisons between PythonDAQ and commercial DAQ solutions, as well as the data acquisition software of a major aero-engine manufacturer are made.
