Data acquisition is the process of sampling signals that measure real world physical conditions. It also involves converting the resulting samples into digital numeric values. It requires values that will be manipulated by a computer. Because it requires a program to run on the computer, as the type of measurement hardware generally varies, and the task generally varies. It generally requires a custom program to be written. Data acquisition software is a computer program developed using various general-purpose languages such as Python, C, VBA (Excel), etc. There are also prewritten software packages, such as LabVIEW. They can provide all the necessary tools to acquire data from different hardware devices. These tools were originally developed for use by the scientific community where complex experiments require fast, flexible and adaptable software. Those data acquisition software packages can also be custom fit in general problems. They can be easily tailored and used in a short amount of time. They can help you see their value vs labor cost.
Graphical programming provides tools & functions to quickly develop applications by graphical programming.
