Design and Fabrication of Automatic Hydroponic System
摘要
This paper illustrates the use of various sensors and pumps to automate the hydroponic system for the farmer’s benefit. Plants need water and NPK fertilizer in appropriate quantities for their growth. There are various hydroponics techniques, among which we are dealing with the Nutrient Film Technique (NFT). In this method, the roots of the plants are suspended over a stream of flowing nutrient solution which provides the optimum level of nutrients to the roots leading to the growth. This automation can be used to increase the yield of crops irrespective of the climate, also improving better yield as compared to the traditional farming techniques. Setup for this system is fabricated to continuously monitor the pH and TDS level. The pH and TDS sensors are used which are connected to the Arduino to collect the pH and TDS levels and to maintain them. This paper states the use of such automated systems to produce crops on a large scale overcoming the traditional problems and increasing productivity. The crop selected for this paper was lettuce (Species: Romania).
