Simultaneous data acquisition - NI DAQ and the Arduino Uno


Data acquisition is in fact meaningless without the proper interpretation of acquired data. As stated at the beginning of this book, data acquisition consists of converting a real-life phenomenon into computer-understandable and human-interpretable data. When we acquire a temperature using a sensor and a DAQ, at one point or another we are converting a voltage (or a current value) into a temperature as adegree. In this process, a sensor that is calibrated within a given specification and accuracy range is connected to a DAQ, which in turn converts the received data (as an input) and communicates the output to a software that ultimately presents it in a human-understandable form; not to oversee the accuracy of the DAQ and the software representation.

What we do in real life is measure the accuracy of a sensor, a measuring device, or a DAQ in our system against another one, that we have more data for and trust more.
