The Problem
Materials lab is cluttered
Need for constant recalibration
Outdated hardware and software
– Slow
– Inconvenient

Our Solution
One device – less wires
Multiple users
Mobility
Cleaner
– Sleek user interface
– Separate tool for calibration

Design Rationale
Major Decisions
– Android or iPhone?
– Bluetooth or Wifi?
![Page 13: Remote Data Acquisition System for Materials Lab Stephen Cauterucio and Corey Simoncic SCHOOL OF ENGINEERING](https://reader036.vdocuments.us/reader036/viewer/2022062517/56649ec45503460f94bcf104/html5/thumbnails/13.jpg)
Test Plan
Alpha Testing (5 phases)
– Android application
– Making Bluetooth work
– Interacting with physical device
– Plotting data
– Saving data
Beta Testing
– Dr. Aschheim and his students

Project Risks
Description P S TI Risk Mitigation Strategy
Lack of Technical Knowledge
.70 .60 .42 -Android Development website -Android programming books-Online Android programming tutorial videos
Lack of Time (Falling behind schedule)
0.5 0.5 0.25 -Cut features-Put more hours into working on the project
Professor Aschheim is too busy to meet with us
0.5 0.4 0.2 -We have set up a standing weekly appointment with him-We can visit during his office hours
Android phones come in many shapes and sizes
1 0.2 0.2 -We will need to pick a good average screen size and develop for that.-If there is time, we may develop app for multiple screen sizes.
