1. Remote Data Acquisition System for Materials Lab Stephen Cauterucio and Corey Simoncic SCHOOL OF ENGINEERING www.scu.edu

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 The Problem  Materials lab is cluttered  Need for constant recalibration  Outdated hardware and software – Slow – Inconvenient

3. Our Solution

4.  One device – less wires  Multiple users  Mobility  Cleaner – Sleek user interface – Separate tool for calibration

5. Requirements  Functional – Transfer sensor data to phone – Phone must display data graphically – Must be able to save sensor data using the phone  Nonfunctional – Device must provide 0-30V of power – Data transfer must be done wirelessly – Only 1 user may have privileges

6. Use Cases  Anyone – Initial device setup  Professor – Starting data acquisition – Viewing data acquisition – End data acquisition – Saving data

7. Use Cases  Student – Viewing data acquisition – Saving data  Anyone – Viewing previously saved data plot

10. Architectural Design

11. Technologies Used  Android Software Development Kit (SDK)  Java Development Kit (JDK)  Eclipse with ADT plugin  Bluetooth

12. Design Rationale  Major Decisions – Android or iPhone? – Bluetooth or Wifi?

13. 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

14. Project Risks DescriptionPSTIRisk 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 0.25-Cut features -Put more hours into working on the project Professor Aschheim is too busy to meet with us 0.50.40.2-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 10.2 -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.
