The Gravity System in the Partitioned Tub as Part of Nutrient Solution Circulation System Using Electronic Controls

Abstract

The nutrient solution circulation system is an important aspect to succeed in hydroponic cultivation. The surface height of the nutrient solution difference in the gravity system is part of the nutrient solution circulation system that uses electronic controls. It consists of a nutrient solution tub with a barrier separating the nutrient solution surface height. The nutrient solution tub is connected via a pipe to a drum containing a nutrient solution where its EC and pH are automatically controlled. The flow of the nutrient solution through the partition is necessary so that there is no shortage of nutrient solution in the tub containing a submersible pump due to pumping.

Irrigation Sluice Control System Using Algorithm Based DC Motor PID And Omron PLC

“…One of the technologies utilized in control is the Programmable Logic Controller (PLC). PLC is an electronic device for controlling various kinds of machines according to programming carried out to achieve certain goals [5]. Therefore, knowledge of PLC which is often used in industry is very important and its utilization is quite wide.…”
