As discussed already, DAQ or Data Acquisition comprises a measurement system and a computer that can measure electrical or physical properties and record them for further analysis.

The concept of DAQ was introduced in 1963 where it mainly revolved around monitoring or controlling a physical entity with software. IBM was the first to announce a computer that was solely made for data acquisition tasks called the IBM 7700 Data Acquisition system.

The IBM 7700 was replaced with a more powerful IBM 1800 Data Acquisition and Control System in 1964. With the progress in technology, the computing capabilities have drastically changed today, allowing us to quickly process and store data in numerous ways.

DAQ systems are an excellent example of this. These devices are capable of capturing data from an actual system and store that data in an easily retrievable format for further engineering or scientific review.

Considering the intuitiveness of the DAQ systems, these computer-based measurement systems are of critical importance in a variety of verticals that need precision, such as construction, electronics, production, and manufacturing to name a few.

DAQ systems are either handheld or can be operated remotely. Handheld DAQ systems are useful when you are required to take readings of a specimen with which you can physically interact. Remote DAQ measurements are taken where human presence is incompatible.

Basic Components of a DAQ SystemThe IBM machines of 1960 where gigantic 6-foot-high computers. Thankfully, the modern DAQ systems are compact, yet many times more powerful than their predecessors.

Years of technological advancements in electronics have made it possible to have such sleek machines that do not compromise on measurement accuracy.

A basic DAQ system consists of four parts:
