Smart Hydroponic System Using Fuzzy Logic Control

Abstract

Hydroponie plant plays a critical role in the agriculture field, which is put forward as a solution to combat climate change. The paper aims to provide automatic monitoring and controlling of hydroponic plants in the greenhouse via smartphones in real-time, to reduce the problems that appear in the greenhouse system and help the farmers in the agriculture process as they still do it manually. The paper will use the nutrient film technique (NFT), the nutrient solution is diluted with the water until getting the concentration for the cultivated plant, and then the excess solution is returned to the tank and watered the plant again. The proposed model will do activities such as measuring the temperature, humidity, and water level in the plant. The system design is based on fuzzy logic, the main objective of using fuzzy logic is to develop automated precise control of the fan and water pump. The proposed model hardware is an Arduino microcontroller, dHT11 sensor, PH sensor, LDR, esp8266 Wi-Fi module, MQ135, water level, fan with 5V, micro-DC water pump, and buzzer. The back end's main functions are to control actuators, provide real-time notifications of the sensor values, and user authentication. The test result of the proposed model is displaying the status of the plant and doing an action, such as controlling fan levels, water pump, and determining the amount of PH needed for the plant. The paper will be organized as the following: first, the background, then related work that is based on the same idea, a proposed model that includes hardware, backend, user interface, and the fuzzy logic system, the paper will end with results of practical work and the conclusion of the paper.
