Design and verification of a solar powered automatic rooftop hydroponic system with real time individual measuring of potassium and calcium
Abstract
This report covers development and implementation of two hydroponic systems. One at a lab inside theUniversity of Agder, and one at the roof on the J-Building at the University. This report tries to answer thefollowing main research question: How can an automated system for control of nutrient concentration andpH in a solar powered hydroponic system be developed, implemented and verified?The focus of the report has been to create a fully functional system for the lab, generating data forelectronic conductivity for measuring a specter of nutrients, pH value, individual nutrients and temperaturefor comparison. The work has been divided into the two systems, where the rooftop system is a much biggerand complex system than the one built in the lab.The approach has been to measure the parameters mentioned above while growing several crops insidethe lab through the period. Knowledge has also been gathered through reviewing already published articlesalong with conferencing with the supervisors. The results have shown two fully functional hydroponic system,where the roof top system is powered by solar power. The results have also provided more data which canbe used regards optimization of lettuce and maybe other plants.i
