Prototype of a Multivariable Measurement System

Abstract

In this work we present the guidelines for the construction of a prototype for general purpose measurements. The goal for this prototype of a virtual instrument is to achieve measurements at macro- or micro-scales, depending on the variables. The measurements will be made through sensors from a personal computer without having to resort to commercial instruments. The system consists of a development platform (Arduino), an adapter to adjust the sensors and a graphical interface. The acquisition card has the specifications required for the correct functioning of the sensors, whereas the adapter consists of different plug-and-play inputs. In our development phase, the regulation of voltage and frequency was tested, as was the communication required for correct readings from the sensors. We obtained a system and an interface capable of recognizing the connected sensors and that showed the measurements in the interface developed in LabVIEW; our system also allowed saving the information (input and output).
