2. 2 MDR ECE 415 Agenda  PDR summary  Design Choice  Technical problems  Deliverables

3. 3 MDR ECE 415 PDR summary  Less expensive than current designs  Portable handheld device  Measure pH, salinity, temperature  Integrate multiple sensors  Data Log capabilities  3 Design alternatives USB storage Bluetooth using cell phone to send email to PC ZigBee protocol to send data to PC

4. 4 MDR ECE 415 Design 1 (USB)

5. 5 MDR ECE 415 Design 2 (Blue Tooth + Cell phone)

6. 6 MDR ECE 415 Design 3 (ZigBee + Computer)

7. 7 MDR ECE 415 Design Choice  Handheld device that will display real time measurements  Wireless transmission using Bluetooth technology  Integrate three sensors pH salinity temperature

8. 8 MDR ECE 415 Why this design choice?  Arduino application has I/O allowing us to integrate sensors and display at a low cost  LCD display for measurement readouts  Bluetooth is more widespread and distance now equals that of ZigBee protocol  USB storage incorporated more extensive knowledge than scope of class
