Question

Difference between data logging and data acquisition

Answer 1

A data logging system involves a logger which records data from one or more inputs (sensors) and either displays or feeds the collected data to a computer to be viewed, analysed and stored by special software.

The data can be used to produce graphs and charts.

Data acquisition systems can be standalone or married to a computer and can acquire multiple channels of data.The electronic signals from the weather station are transmitted to the data acquisition system where they are interpreted and stored for collection on a periodic basis.A data acquisition system is a system that acquires data, generally by digitizing analog channels and storing the data in digital form.

Hellloo!!

Data logging : Data logging is the collection of data over a period of time, and is something often used in scientific experiments.Data logging systems typically monitor a process using sensors linked to a computer. Most data logging can be done automatically under computer control.

Data acquisition : Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound with a computer. A DAQ system consists of sensors, DAQ measurement hardware, and a computer with programmable software.
