AUTOMATIC CONTROL SOLUTIONS FOR AGRICULTURAL SYSTEMS OF ARTIFICIAL LIGHTING AND HYDROPONIC HARVEST

Abstract

This paper mentions solutions for agricultural systems of artificial lighting and hydroponic harvest. Artificial lighting system will be regulated by switching blue, red and ultra violet LED lamps on/off corresponding to growing periods of plants. In this system, water pumps will be also regulated to change their speed basing on measured information about environment temperature and soil humidity to change between drop-by-drop mode and high speed mode. Moreover, automatic control for some stages of hydroponic harvest, from the stage of picking up the substrate to the stage of dropping the substrate onto the conveyor belt, will be also proposed in this paper. Two experimental models will be introduced and created in the laboratory to make clear research results. They will show the feasibility of proposes for agriculture systems. Contributions of this paper will be continued to develop and complete to apply in real agriculture systems.
