An Introduction to Data Acquisition

Data acquisition in its simple terms means the generation of data with the use of a computer. It is also referred to as DAQ or DAS. Aside from the data itself, it also obtains waveforms and signals. These key components are then used to acquire certain information.

One key component of a data acquisition system is a sensor. A sensor can efficiciently convert any measurement parameter into readable electric signals. A data acquisition gadget then acquires these signals and converts them to comprehensible information.

Data acquisition systems may use a number of common programming languages which includes:
· Java
· Lisp
· Pascal
· EPICS
· BASIC
· C
· Fortran

The role of data acquisition system is to analyze, display and to store the acquired data on the users computer.
