Data Acquisition (general):

Data Acquisition: software:


  • Comedi: a project that develops open-source drivers, tools, and libraries for data acquisition.

  • EPICS: is a set of Open Source software tools, libraries and applications developed collaboratively and used worldwide to create distributed soft real-time control systems for scientific instruments such as a particle accelerators, telescopes and other large scientific experiments.

  • Midas: a data acquisition system under the GPL which is used in particle and nuclear experiments. The software contains a library which can be used for data transport between different computers and programs, and a set of programs for data logging and system management.

  • Zephyr Measurement System: "a script-driven data acquisition and measurement automation program written in Java. It has been developed to simplify some laboratory tests at Nanomix. it's also being used by the Star Research Group at the University of Pittsburgh. This program may be suitable for many other applications involving measurement instruments and actuators, especially where there's a need to change the setup often. The most important feature of this program is scripting, which allows scheduling of configuration and measurement events. The script language is based on XML. The script interpreter, instruments and output components are loosely coupled in this program, which allows it to be quite flexible."

Various Articles on Data Acquisition Systems:


Teaching and Education:



  • SCADA overview (Stanford University) -- History, Benefits, SCADA System in Action.

  • SCADA Primer

  • SCADA Explained -- An FAQ-style guide to SCADA basics. "The primary purpose of SCADA is to monitor, control and alarm plant or regional operating systems from a central location."

  • SCADA Stuff -- Links, Books, Software and Hardware vendors.

  • Alavu: is a free, open-source SCADA (supervisory control and data acquisition) software package. It acquires data at the rate of 1 sample/second for 10 minute interval. Provides different views for the acquired signal in IntervalMap, InstantMap and VirtualMap. Enables to classify signals in to different views in ClassEdit. Collects data from remote server. Logs data of all channels every hour for the one week duration. Gives Statistical report and Fourier Spectrum of logged data.
