Remote Data Acquisition using Bluetooth David R. Loker, P.E. Collin G. Frampton, Titan J. McElhaney, Jonathan R. Mook, Anthony M. Sansone Penn State Erie, The Behrend College
In this paper, a remote data acquisition project using Bluetooth technology is presented for a senior technical elective telecommunications course in the Electrical Engineering Technology Baccalaureate Program at Penn State Erie, The Behrend College. There are several noteworthy characteristics of this project. First, the project used two Bluetooth modules which were each interfaced to a computer through an RS-232 port. Second, LabVIEW was used as the software development environment for communicating with the Bluetooth modules and for automatically uploading and downloading information from a data collection process.
The system requirements for the remote data acquisition project consisted of a local computer and a remote computer, simulating an environment for remotely collecting data. Each computer contained a Bluetooth module that was configured as either a master or a slave. The master initiated the establishment of a communication link with the slave, and the slave responded to the master. The local computer executed a LabVIEW program that configured its Bluetooth module as a master. The remote computer, which contained a data acquisition board for data collection, executed a LabVIEW program that configured its Bluetooth module as a slave.
The purpose of the local computer was to transmit control information for the data collection process to the remote computer. This information included the number of samples, the sample rate, and the acquisition mode. The purpose of the remote computer was to acquire the proper number of samples at the appropriate sample rate and to automatically upload the data to the local computer. Once the remote computer uploaded the data, it was downloaded at the local computer and displayed on a graph.
Results from both the local and remote computer programs are presented in order to verify that the functional requirements of this design project were satisfied. Results from a student assessment form are also presented. Conclusions and recommendations regarding the educational benefits of using this design project within a Baccalaureate Electrical Engineering Technology program are discussed.
I. Introduction to the Project
A senior technical elective course in telecommunications is offered as part of the Baccalaureate degree in Electrical Engineering Technology at Penn State Erie, The Behrend College. There are two prerequisites for this course. The first prerequisite is a junior level communications systems course which emphasizes an introduction to analog communication techniques. The second prerequisite is a junior level measurements and instrumentation course which introduces "Proceedings of the 2005 American Society for Engineering Education Annual Conference & Exposition Copyright 2005, American Society for Engineering Education"
