The document proposes the development of a fully automated greenhouse system using Raspberry Pi to control sensors and automation. It aims to produce pesticide-free fruits and vegetables in an efficient and cost-effective manner. The system was tested growing strawberries with positive results, showing increased yields from precision environmental control including temperature, humidity, CO2 and moisture levels. The automated greenhouse could produce up to a metric ton of tomatoes per season in a small 2.5x3m space with 40m2 of growing area. Future work involves building a 1:1 prototype and starting a business to commercialize the system.

4. Problem
 The quality of vegetables and fruit bought at
the store is rapidly decreasing
 The better quality products contain a lot
pesticide residue
 This annoys a lot of people
 It can be dangerous

5. The Solution
 Creating a fully automatic greenhouse, that complies with the following
principles:
 It shall be based on the Raspberry Pi
 It shall be cost-efficient
 It shall be easy to use
 It shall be modular
 It shall be controllable from any internet-connected device

13. Research results
 The properties of photosynthesis IN C3 plants
 It is blocked by the presence of oxygen
 25 ºC is the optimal temperature
 It only uses CO2 at night
 The optimal level is 800-1600 ppm
 The plants only need 50-60% of the sunlight getting to them through an average
greenhouse wall
 Staircase-style arrangement is not needed ► more income can be achieved by using a shelf-
style arrangement

14. The Features
 Pesticide free plant production made easy
 Automatic temperature control(Heating, Ventilation)
 Vegetation heating ► Dry plants ► No Infections
 Precision Soil Moisture control(Micro drip system)
 Automatic CO2 injection
 Built in weather station
 Shelf-style arrangement ► 40m2 of effective farming area
 Up to a metric ton of tomatoes per season
 All in a 2,5x3m greenhouse
