Fuzzy Logic-Based Automatic Water Quality Control System in Smart Aquaponics

Aquaponics is an advanced farming technique that relies on continuous water flow between aquaculture and hydroponic components. The success of this system is determined by the maintenance of the specific water chemistry to ensure sustainability and proper operation. The automated water quality control can greatly assist farmers in efficiently managing water conditions. To achieve this, an aquaponics water quality control system is required with a focus on monitoring and regulating parameters such as dissolved oxygen (DO), total dissolved solids (TDS), and pH levels. The DO control involves the use of pumps to increase DO levels in water; TDS control uses pumps to deliver nutrient mixtures to increase TDS and pH control utilizes pumps to flow and adjust pH levels. Fuzzy logic methods are employed to process data in the development of this control system. The results indicated that the fuzzy method can regulate the operation time of various pumps based on the input values of DO, TDS, and pH. Even under extreme conditions, the control system can effectively regulate the actuators.
