With the progress in technology, the computing capabilities have drastically changed today, allowing us to quickly process and store data in numerous ways.ĭAQ systems are an excellent example of this. The IBM 7700 was replaced with a more powerful IBM 1800 Data Acquisition and Control System in 1964. IBM was the first to announce a computer that was solely made for data acquisition tasks called the IBM 7700 Data Acquisition system. The concept of DAQ was introduced in 1963 where it mainly revolved around monitoring or controlling a physical entity with software. Important applications of the DAQ systemĪs 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.Factors affecting the measurement accuracy.Together, these components form a Data Acquisition System or DAQ System. In essence, data acquisition is a process that involves collecting information to understand the electrical or physical phenomenon using sensors, measurement device, and a computer. Another example is measuring and recording the current difference across a resistor. A simple task as measuring and recording the temperature is as Data Acquisition. Without data, we wouldn’t be able to understand how a system actually performs.įor example, if you want to set up a heating coil that can help the object to reach a specific temperature, you cannot understand its level of success without measuring the temperature. With any project or experiment that you undertake, the data that it produces will ultimately determine the fruits of your labor. A Complete Guide to Data Acquisition (DAQ) Systems
