Automated System that Monitors and Controls the pH and Electrical Conductivity of a Closed-Hydroponic Setup

The Automated Closed Hydroponics System relates to a system that monitors the pH and electrical conductivity (EC) of the nutrient solution. It is constructed to modify and optimize the conventional hydroponic system as determined through its specific operational requirements to utilize the system safely and profitably. The modules are electronically integrated into the system that continuously monitors the pH level and the EC level of the nutrient solution and automatically adjusts its content to the proper range suitable for the plant used. The developed system lessens human involvement, and in turn, eliminates human error while keeping expenses at a minimum and ensuring yield at maximum. This article discusses the operation of the system which consists of the reservoirs for the dispensing of acid, base, nutrient solution, and water, with its necessary valves, motors, hose, and flow regulators; level sensors installed to the reservoirs to monitor the refilling requirement and operational conditions; pH monitoring and control; electrical conductivity (EC) monitoring and control; and, the nutrient uptake analysis to illustrate the plant nutritional status verifying that the plants were taking up the nutrient balance they require when the pH and EC are on their respective exact levels. The automation in the hydroponic system results in a more balanced culture, creating healthier and more homogeneous leaves
