Design and Development of Aeroponic Growing Control System for Red Coral Lettuce

Abstract

Crop cultivation requires detailed control and management to ensure desired growth. Red coral lettuce is a popular salad vegetable and an economically important crop. Farmers or individuals who wish to grow this type of lettuce using hydroponics need to control the quantity of dissolved nutrients, as well as the pH and EC (Electrical Conductivity) values of the water to meet the plant's requirements. Monitoring and controlling these various parameters manually can be challenging and not comprehensive. Therefore, this project aims to design and develop an aeroponic-controlled system for growing red coral lettuce. The developed control system can automatically adjust the pH and EC values of the water to create an optimal environment for growing red coral lettuce. The system consists of a microcontroller working in conjunction with pH sensors, water level sensors for bottles and tanks. Users can monitor and adjust the control settings they desire through the Blynk application. The test results have shown that the pH and EC values can be automatically controlled according to the desired parameters.
