2. The Team Simeon Eisen, Aaron Maley, Jeff Overweg, Jacob Vander Wall

3. The Problem Owning a Pool Requires a lot of Work Traditional Chemical Test Methods are Imprecise Improper Pool Care could result in Eye and Skin Irritation Your Time is Valuable

4. Project Overview Create an automated Pool Chemical Regulation System. Monitor both pH and ORP(Oxidation Reduction Potential) Mechanically Add Chemicals to regulate the pool. Give basic control and vital updates via web/Smartphone interface.

5. Microprocessor Sensors Dispensor PH+, PH-, Sanitization Signals Analog PH, ORP Signals, Temp Online Interface Data, Alerts Local Interface

6. Project Background Current Models Exist: Mostly for the Commercial, Industrial and High End Residential >$2000 Our Goal Create a system for the Residential Market Use Solid Granulized Chemicals Web/Smartphone based Controls and Updates <$1000

7. Project Market United States 5.1 million in-ground pools 3.7 million above-ground pools Canada 404,000 in-ground pools 253,000 above-ground pools Large Market for our Product in North America alone.

8. Design Intentions Trust Our customers must be able to rely on our product. Transparency The design must be simple to understand and operate Stewardship Proper use of time and resources Integrity End Product must meet customers need

9. Project Status Working with BUS 396 Team to develop Market Plan. Taking Testing Data using pH and ORP probes Developing Contacts with the physical plant dealing with Calvin’s Pool Maintenance Selecting Mechanical System for Solid Chemical Dispersal Testing/Developing Microchip Controller Researching Wireless Website Update and Data Monitoring
