What is Data Acquisition?

Definition and meaning of Data Acquisition

Data acquisition is the technique of measuring physical international situations and phenomena consisting of energy, sound, temperature and stress. This is perFormed via the usage of diverse sensors which sample the environment’s Analog Signals and rework them to Digital indicators using an analog-to-virtual converter. The ensuing digital numeric values can then be without delay manipulated by a Computer, taking into account the analysis, garage and presentation of those statistics.

What Does Data Acquisition Mean?

Data acquisition is often carried out using a aggregate of gadgets and equipment that form a information acquisition sySTEM (DAQ or DAS). The DAS samples the environmental indicators and transforms these to Device-readable signals, while the Software Program processes the acquired facts for Storage or presentation.

There are 3 additives required for facts acquisition:

• Sensors which are able to seize environmental analog signals like temperature, strain, light or sound
• Signal-conditioning Circuitry that normalizes Captured indicators; Noise reducers and amplifiers are properly examples
• Analog-to-Digital Converter that converts the conditioned signals into digital facts

Specific DAQs are frequently created for particular bodily homes. For Instance, there are devoted structures for measuring simply temperature or simply strain, however smaller dedicated information acquisition structures may be integrated into a larger machine via Software program with the aid of absolutely taking the facts accumulated by way of those person structures and providing them to the person.
