Abstract [en]

The purpose of this project is to make it easier to grow plants domestically all year round. The objective is to construct a remotely controllable and environmentally independent automated hydroponic system. This would minimize the efforts required by the user to sustain plants in non-native climates.

A hydroponic gardening system uses water as a growth medium instead of soil. The system is climate conscious and has benefits compared to conventional agriculture.

Hydroponic systems are affected by several factors, this project only focuses on controlling the light intensity by isolating the system, and regulating the nutrient concentration through EC. The system uses a microcontroller for analysis and control.

The results are promising, showing that the system works. However, the limitations in time led to a short test period, therefore the data gathered is limited. The discussion based on the results conclude that the system cannot be considered completely automatic but reduces the need of manual labour.

Abstract [sv]

Syftet med detta projekt är att göra det lättare att odla växter inhemskt året runt. Målet är att konstruera ett fjärrstyrbart och miljöoberoende automatiskt hydroponiskt system. Detta ska minimera ansträngningarna från användaren för att underhålla växter i icke-inhemska klimat.

Ett hydroponiskt odlingssystem använder vatten som tillväxtmedium istället för jord. Tekniken har fördelar jämfört med konventionell odling vilket gör hydroponi mer miljövänligt.

Hydroponiska system påverkas av flera faktorer, men detta projekt fokuserar bara på att kontrollera ljusintensiteten genom att isolera ljuset inom systemet samt att reglera näringsämne-koncentrationen genom att mäta den elektriska ledningsförmågan i vattnet. Systemet använder en mikrokontroll för analys och kontroll.

Resultaten är lovande och visar att systemet fungerar. Däremot har begränsningarna i tid lett till en kort testperiod, därför är data som samlas in begränsad. Diskussionen baserad på resultaten drar slutsatsen att systemet inte kan anses vara helt automatiskt men reducerar behovet av manuell arbetskraft.
