Data Acquisition using LabVIEW

By: Behzad Ehsani

Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

Arduino photo sensor board


We are now ready to go through an example. The purpose of this example is to illustrate that finding and installing libraries and drivers is a routine part of data acquisition. Arduino sensor kits provide about 40 boards and sensors for about $40 from Amazon (for example) but if you spend the required time and effort, you may buy the same sensor packs much cheaper on eBay or other resellers found on the internet. Complete source code and pictures of the Front Panel and Block Diagram are provided. The aim is to have the reader acquire and install the rest (IDE, drivers, and firmware) to emphasize the fact that nowadays most of the drivers and the latest instructions for almost any instrument reside on the internet and diver hunting and installing is an "art" that must be simultaneously acquired during learning data acquisition!!

In this example, we will use the following:

  • An Arduino Uno R3:

  • A photo resistor sensor board:

Hardware connection:

  1. Connect the center pin...
