Abstract - These days, soil-based agriculture faces
technique in order to introduce dissolved oxygen to the water, as a deficiency in oxygen will hinder plant roots' ability to absorb nutrients. For plants to maintain their nutritional needs, nutrient solutions must be available to them constantly. The productivity and quality of lettuce grown in hydroponic systems are significantly influenced by nutrition. Determining the quality of lettuce products requires a balanced absorption of nutrients [2].
challenges from a variety of man-made factors, including urbanisation and industrialization. The decrease of soil fertility and quality is also a result of uncontrolled chemical usage in agriculture, abrupt natural disasters, and climate change. Because of this, researchers have created a brandnew alternative farming method known as soil-less agriculture, or hydroponics. Plants can be grown hydroponically in a nutrient-rich, water-based solution. Many different plants, crops, and vegetables can be grown with hydroponics. When compared to natural soil-based cultivation, hydroponically produced final products typically have greater quality yields, tastes, and nutritional values. This type of agriculture is becoming more and more wellliked worldwide, in both developed and developing nations, and it is also inexpensive, disease-free, and environmentally benign. In many nations, it has excellent prospects in conjunction with advanced space research to address the scarcity of arable land in situations when suitable cultivable land is unavailable. Therefore, hydroponics would be a better method to meet the demand for nutrition in the world while also producing a variety of fruits, vegetables, and feed while advancing the future. Hydroponics may become one of the new methods used in the future to feed the world's population.
2. LITERATURE SURVEY [1].”A survey of smart hydroponics systems” by Fatmata M, Mahdi Musa and Farouq Aliyu : The paper goes on to explain the basics of hydroponics and the various ways in which the system can be implemented. The authors have tried to create as automated model and have tried to find out the optimal root zone of crops such as lettuce. the study Automated system developed to control pH and concentration of nutrient solution evaluated in hydroponic lettuce production carried out control of pH and the concentration of plant does not die. [2].“Cost effective smart Hydroponics Monitoring and Controlling System Using IOT” by Ullah and A Aktar: The paper presents a cost-effective IoT-based system for monitoring and controlling hydroponic farming parameters such as water level, pH, humidity, and temperature through a mobile application. The literature survey highlights the innovation and improvement in nutrient solution level control for DWC hydroponics, addressing previously overlooked areas. The proposed system leverages modern technology to enhance the efficiency and reliability of hydroponic farming, contributing to better crop management and higher productivity.

1.INTRODUCTION The agricultural industry is crucial. However, as technology advances, the industrial sector is growing as well. The narrowness of agricultural land is impacted by the rise. One possible way to solve these issues is to implement a hydroponic system. agricultural method. Hydroponics is a technique for growing plants that uses water as a planting media instead of soil and a fertiliser solution that the plants require. Deep Water Culture (DWC) is one of the community's hydroponic methods. DWC is a hydroponic method that feeds plant roots with nutrient solutions directly. The plant's root will always be immersed in a nutritional solution thanks to the DWC technology [1]. This kind of hydroponics, called Deep Water Culture, enables indoor or boxed planting. When planting inside a box, TL lamps can be used in place of natural sunlight. Aerated nutrient solutions are necessary in this DWC hydroponic

[3].In the study “A Development of automatic Microcontroller System for Deep Water Culture pH control on DWC hydroponics uses a pH sensor as a reader of the pH value in solution. In addition, in this study also paid attention to the level of nutrient solution by flowing water into and out of the reservoir. In this study, monitoring the level of nutrient solution is important to maintain the level of nutrient solution that is appropriate to the reservoir. But monitoring still uses LCDs and remote monitoring and control cannot be carried out. In the study Electrical Conductivity and pH Adjusting System for Hydroponics carried out control of the concentration of nutrient solution and pH using linear regression method on red lettuce and green lettuce.
