  1. Poseidon Pool Care

    Calvin College Senior Design Team 11 Aaron Maley Jeff Overweg Simeon Eisen Jacob VanderWall
  2. A Niche in the Market There are current pool care systems, but they are not created and marketed to the average residential pool owner. Current systems range in price from $1200-$7000 for just the controller alone A product with the features of the high end systems, at a price that residential pool owners can afford would be a very viable real world product
  3. The Project To create an affordable chemical control system for the residential pool market. What Does it Do? Sample pool water at regular intervals Microprocessor controlled system Dispense chemicals into the pool pump system Granule feed system Broadcast pool data via website Wireless module
  4. Microcontroller System Goal: Use an embedded microcontroller to control water testing, chemical dispersal, local display, and data being sent to web server. Major Components and Interfaces: Sensors and Related Circuits Chemical Dispersal Control Local Display/User Interface Analog Data to Web Server
  5. Microcontroller System Full System Diagram
  6. Microcontroller System Sensors and Related Circuits Four main sensor inputs Temp, pH, ORP, Chemical Level How are the amounts of Chemicals Needed Calculated? Tested regularly (user defined) and dispersed down to 0.7 oz precision Based on Free Chlorine Calculation and pH readings
  7. Free Chlorine Calculation
  8. Microcontroller System Local Display/User Interface Graphic LCD Touch Screen Interface What does this allow the user to do? Directly view relevant information Calibrate probes and sensors Define parameters such as: Pool Volume Pump Cycle Time pH/ Free Chlorine Thresholds Chlorine “Shock” frequency
  9. Microcontroller System Data to Web Server Analog Level Created with: PWM signals passed through a low pass filter How does the Web Server Interpret Values? Varying Duty Cycles Form Different Voltage Levels Communication Specification for Analog Interpretation Defines Relationships
  10. Microcontroller System Chemical Dispersal Control Digital Control Logic (Stepper Motor Control) Solenoid Valve Channel Control How the System Disperses the Chemicals
  11. Instrumentation Setup Sensor Chamber Design
  12. Dispenser Goal: To create an interface that would utilize the existing pool pump and filter system to dispense and mix chemicals into the pool water. Two distinct elements Auger Based Dispenser Diverted Mixing Chamber
  13. Mechanical Setup Final Mechanical Implementation Pool Dispenser Pump Filter Mixing Chamber
  14. Mechanical Setup Dispenser System Design
  15. Mechanical Setup Actual Dispenser
  16. Dispensing Calibration
  17. Stepper Motor and Solenoid Control
  18. Wireless Web Server Goal: To create a basic web server in order to wirelessly broadcast system readings to the consumer. Main Components 802.11b Chip/Security Settings Analog Input/Calculations Website Design
  19. Wireless Web Server 802.11b Chip/Security Settings Chip/Development Board Selection Arduino Development Kit Wishield Security Capabilities Compatible with modern 802.11b/g routers Can utilize 64bit WEP, WPA, WPA2 encryption
  20. Wireless Web Server Analog Input Calculations Varying Duty Cycles + Low Pass Filter Analog Voltage 0V – 5V Communication Specification Determines pH, ORP, Chemical Status, Temperature Calculation of Free Chlorine PWM Low-Pass Filter + = 0-5 Volts Analog
  21. Wireless Web Server Website Design Theoretical Design
  22. Wireless Web Server Actual Page Design
  23. Wireless Web Server System Block Diagram
  24. Budget Total Project Budget Originally given $300 for budget Granted additional money at start of 2nd Semester
  25. Competitive Analysis Main Competitors: Chemtrol CAT Aquasol
  26. Sales & Marketing Customer Base Existing( US alone) 5.1 million in-ground pools 3.7 million above-ground pools Growth( Based on 2007) 131,000 new in-ground pools 233,000 new above-ground pools Target Demographic Work with BUS 397 Advanced Marketing Class Middle-aged to Elderly in Average Middle to Upper Middle Class Homes
  27. Going Beyond Different ways project could be enhanced or developed further. Expand Wireless Capability and Complexity Add Online Data Logging Add Wireless System Control Use Precision Designed Mechanical Parts Integrate onto single PCB Develop Business Plan as a Distributer and/or a Supplier
