Nutrient Film Technique based Hydroponic System Using Fuzzy Logic Control

Vegetables are nutrients that are needed by the human body. The Nutrient Film Technique (NFT) based Hydroponic system is typically used to produce vegetables on small farms that can accelerate the harvest time with high-quality products. One of the most important parameters in hydroponics is the providing of appropriate amounts of nutrients based on the age of the plant. In this study, the NFT-based hydroponic system has been designed by using fuzzy logic control. The set point value of Electrical Conductivity (EC) of the nutrient solution is predicted by image processing of HSV Histogram of the pakcoy mustard plant. The result of the experiment showed that the fuzzy logic control has been able to provide nutrients in accordance with the age of the plant with an error rate of 8.9%.
