Data Acquisition Systems


The components of data acquisition systems include:

  • Sensors that convert physical parameters to electrical signals.
  • Signal conditioning circuitry to convert sensor signals into a form convertible to digital values.
  • Analog-to-digital converters, which convert conditioned sensor signals into digital values.

Data acquisition applications are controlled by software programs developed using various general purpose computer programming languages, such as BASIC, C, Fortran, Java, Lisp, & Pascal.

Specialized software tools used for building large-scale data acquisition systems include EPICS. Graphical programming environments include ladder logic, function block, Visual C++, Visual BASIC.
