Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS or DAQ, typically convert analog waveforms into digital values for processing. The components of data acquisition systems include:
– Sensors, to convert physical parameters to electrical signals.
– Signal conditioning circuitry, to convert sensor signals into a form that can be converted to digital values.
– Analog-to-digital converters, to convert conditioned sensor signals to digital values.
