[attachment=17688]

What is data acquisition and data logging
Data acquisition is simply the “gathering of information about a system or process”
Information may be gathered for various reasons
knowledge
research and development
systems or process monitoring
systems or process control
Data acquisition requires one or more transducers (sensors) to sense the system or process, and a signal measuring instrument

What is data acquisition and data logging?

Data acquisition and data logging is not a complex or mysterious science as viewed by some

Data acquisition in its simplest form could be to measure the length of a piece of string with a ruler

Data logging in its simplest form could be to write that measured length down on a sheet of paper


A data acquisition or data logging system

A data acquisition or data logging system generally includes the following components:
sensors or transducers which provide the fundamental information of the parameters to be measured
a device to convert the primary signal from the sensors into a form compatible with information processing systems
a computer or other controller which supervises the overall system, and manages the generated data
