Study of the Growth Parameters of the Plants in Hydroponic System and Design of Adaptive Control System

Abstract

This project presents a hydroponics system design and control variable. The objective is to reduce the time to transplant. To controlling the parameters that plants need to be in proper condition to photosynthesis. Which is resulting in cost savings in the plants. The research begin to grow crops and store the parameters. Next is to analyze the parameters, there are four parameters, the conductivity value, the pH value, the temperature value and the sunlight to design the control systems. Experiments done on the crops for x set. There are 3 parameters, the electrical conductivity, the pH and the temperature, they were stored before planting and after planting to the control system design. The experiment results of the control electrical conductivity and the pH control have to change due to sunlight. Because the plants need it for photosynthesis nutrients thus the electrical conductivity decreases. For pH control, the pH value has changed a little due to the absence of sunlight and the pH value changed to the acid because plants release the substance. For the temperature control, it doesn't have changed. The experiment results of all plants are growing faster as acceptable. This project is a useful guide for teaching in the fields of instrumentation and can be used to perform a series of field instrumentation has.
