  • 3. INTRODUCTION • Network-enabled devices are becoming increasingly ubiquitous • Embedded development platforms have become extremely affordable • Devices controlled via internet make it possible to administer a complex housing operation remotely Arduino - $25 Raspberry Pi ® - $37 Beagle Board - $90
  • 4. INTRODUCTION • Wide variety of applications • Reliable Facility Security • Distributed Preventative Maintenance • Efficient Utility Monitoring • Automated Facility Upkeep We will be focusing on the final example
  • 5. TABLE OF CONTENTS • Introduction • Project Overview • System Layout • Related Projects • Conclusion
  • 6. PROJECT OVERVIEW • Problem • Multi-family pool systems are maintenance-intensive • Algal growth and sanitation are primary concerns • Water must be tested at least daily • Manual tests require non-recoverable testing supplies • Impossible to gather high-resolution chemical data with manual tests • Manual test results are prone to (potentially costly) human error
  • 7. PROJECT OVERVIEW • Objective • Design remotely-accessible automated water chemistry testing and data logging system • Upgradable to supply chemicals & become a self-maintaining system • Streamline pool maintenance process • Save time, increase measurement precision • Collect data for analysis of chemical levels over given time period
  • 8. TABLE OF CONTENTS • Introduction • Project Overview • System Layout • Related Projects • Conclusion
  • 9. SYSTEM LAYOUT • Sensor Platforms • Based on popular Raspberry Pi ® Linux computer • Installed in multi-family pool complexes • Connected to nearby Wi-Fi network • Continually test water chemistry • pH • Oxidation Reduction Potential (ORP) • Water temperature ORP Sensor Probe pH Sensor Probe
  • 10. SYSTEM LAYOUT • Sensor Platforms • Display real-time readings on external LCD display • Log results to USB flash drive for data redundancy • Communicate results to central server via internet • Has connectivity for future chemical dosing pumps Miniature ORP probe interface SparkFun 20 x 4 LCD Display
  • 11. SYSTEM LAYOUT
  • 12. SYSTEM LAYOUT • Central Server • Also based on Raspberry Pi ® • Gathers real-time results from distributed sensor platforms • Logs data on local USB flash drive • Displays both real-time and logged data on a web page • Accessible from PC or mobile device • Arranges data graphically over time • Remote addition of water, sanitation chemicals can be controlled via same web interface OR by pre-programmed setpoints Miniature Wi-Fi adapter for Raspberry Pi
  • 13. TABLE OF CONTENTS • Introduction • Project Overview • System Layout • Related Projects • Conclusion
  • 14. RELATED PROJECTS • Security • Networked video cameras to provide automatic and remotely-accessible surveillance • Preventative Maintenance • Wireless, distributed thermostats to aid in vacant apartment freeze protection • Efficient Utility Usage • Internet-enabled water chemistry testing and balancing system to automatically maintain water quality for swimming pools, water features, and potable water supply
  • 15. TABLE OF CONTENTS • Introduction • Project Overview • System Layout • Related Projects • Conclusion
  • 16. CONCLUSION • It is possible to design and implement low-cost network-enabled devices • Devices allow for greater degree of control over facility operation • Automation saves time, increases overall efficiency
