  1. Final Project Review Team 3 Gro-Bro April 13, 2017 Advisor: Professor Jackson Michael D’Anna, Samantha de Groot, Maxwell Joyce and Shaun Palmer

  3. The Problem • Widespread access to local produce • Food deserts • Reduce carbon footprint of shipping • For people without the time, space and knowledge to garden

  4. Our Solution: Fully Automated Smart Greenhouse • Array of sensors inside greenhouse • Continuous measurements • Displays information on app • Sensor data used for the water pump and nutrient dispersal control

  5. Block Diagram

  6. Specifications • Automated ✓ • Lighting control ✓ • Hydroponic watering ✓ • Nutrient dispersal/pH regulation ✓ • Closed loop system to recycle water ✓ • Must fit inside of a studio apartment ~(2’x4’) ✓ • Yield 6 fruiting plants ✓ • Reusable ✓ • App with simple UI – easy for people to use and learn ✓

  7. FPR Deliverables • Yield 5-8 fruiting plants ✓ • Make the structure more aesthetically pleasing – add logo and finishing touches ✓ • Finalize android app GUI ✓

  8. Android App Improvements

  9. Control Unit Improvements • Added log files to keep track of every action performed • Now remembers exact state- hours since last watering, lights • Sensors • Repaired oxidized hygrometers • Added BJT circuit to turn on only when taking measurement

  10. Greenhouse Performance vs. Control Plants

  11. Greenhouse Performance vs. Control Plants

  12. Cost Analysis • Cost to make greenhouse: ~$925 • Operation of greenhouse: 4.2 kWh per day • At $0.12/kWh electricity cost and 60 days to grow tomatoes, costs $30.24 to grow 6 tomato plants, which each yield ~12-15lb of tomatoes = ~80 lb total • Nutrients cost ~$15 per 60 days = ~$45 total for 80 lb of tomatoes … ~$0.56/lb • Store-bought tomatoes average ~$2.00/lb

  13. Cost Analysis… Break even after 642 lb of tomatoes = 8 (60 day) seed to harvest growth cycles If spacing cycles 1 month apart, takes 2 years to break even

  14. Questions? • ???

  15. Project Demonstration • Time lapse video • Show plants • App demo

  16. Time Lapse Video
