Presentation Transcript

  1. Post PC Irrigation Sensor Post PC Computing, HUJI 2001 Lecturer: Prof. Scott Kirkpatrick Presented by Ami Serri-Menkes

  2. Overview • Introduction • Critical Tasks • Technology Requirements • Usability Issues • Conclusion

  3. Current Needs • Water Conservation • Energy Conservation • Green Areas: Agriculture Horticulture Nature Reserves

  4. Project Goals • Low Power Irrigation Controller • Smart Sensor Input • Weather Forecast Input

  5. Description • Solar Irrigation Computer • Smart Sensors: Solar Panel Tensiometer - ‘Artificial Root’ • Solenoids – Electric Valves • Future: Internet Weather Forecast

  6. Competitive Analysis • Competitors • Manual Irrigation • Timer-based Irrigation • Strengths • Water Use Efficiency • Weaknesses • Price of Connectivity, Components

  7. Technology Requirements • Power Budget: • 9V battery: 5.085 WHr • Solar panel: 12-30WHr/Day • Power Consumption: • 1 Solenoid: 14mWHr/Day • 4 Solenoids: 64mWHr/Day. • CPU+Display: 7mWHr/Day • Tensiometer: 3mWHr/Day. • Cellular: 25mWHr/Day (listen mode) • Total: 100mWHr/Day

  8. Data Integration • Time-based to Tension-based • Depends on Plants, Soil Type • => Calibration:min,max

  9. User Testing • (video clip)

  10. Usability Issues • 3 Modes: Sensor,Auto-run/off,Manual • =>2 Modes: Sensor, Manual • On/Off buttons confusing • =>STN button or new Mode button

  11. Future Work • Component and Data Integration • Cellular Connectivity (SMS?) • New Sensors (LeafSense) • Usability

  12. Conclusion • Present: Prototype (non cellular) • Future: Connected • Energy, Water, Fertilizer Savings • Time Savings

  13. What We Learned • How to Develop Ideas • Technical Analysis • User Testing • Solar Power • Irrigation
