Data Acquisition (DAQ)

Hans-Petter Halvorsen

What is DAQ?

Data Acquisition (DAQ) is the process of collection data from different sensors into a computer.

A DAQ System consists of 4 parts: Physical input/output signals, sensors DAQ device/hardware Driver software Your software application (Application software).

The purpose is to read and write data using a DAQ device where we use LabVIEW, Visual Studio/C# or Python. We will exemplify by using a DAQ device from NI. We will use a DAQ devices called TC-01 and USB-6008 (which is part of the USB-600x low-cost series). DAQ devices from NI use the NI-DAQmx driver. Examples shown will work on all DAQ devices from NI that are using the NI-DAQmx driver. The principles used can also be applied on other DAQ hardware from other vendors.

Below you find lots of Tutorials and Examples in LabVIEW, Visual Studio/C# and Python.

 

DAQ in LabVIEW

LabVIEW is a powerful tool for making Data Acquisition applications. Below you find some useful resources.

DAQ in Visual Studio/C#

Data Acquisition in Visual Studio and C# using USB-6008 as an example. In Visual Studio/C# you can use the most of the DAQ hardware from NI since the DAQmx driver also supports Visual Studio/C# programming.
