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 with the acronymDAS or DAQ) typically convert analog waveforms into digital values for processing.Charge redistribution to achieve A/D conversion. In typical applications, as a ratiometric conversion system for a microprocessor, V^p, will be connected to ground and VREF  will be connected to Vcc.The output will then be a simple proportional ratio between analog input voltage and Vcc.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 that can be converted to digital values;Analog-to-digital converters, which convert conditioned sensor signals to digital values.Data acquisition applications are controlled by software programs developed using various general purpose programming languages such as BASIC, C, Fortran.
