Design of an Internet of Things (Iot) Based Smart Irrigation and Fertilization System Using Fuzzy Logic for Chili Plant

Proper monitoring and control of irrigation and fertilization system is crucial in agriculture field to ensure sufficient nutrients and moisture supplied to the plant is maintained all the time. There are two type of parameters being monitored which are soil moisture and its pH level. A systematic approach in monitoring and control of these parameters is thus necessary to uphold sustain smart farming solutions. Main objective of this project is to design smart irrigation and fertilization system for chili plant using Fuzzy Logic. In this project, the implementation of Internet of Things (IoT) also included where Wi-Fi node is used for the means of connection medium. Fuzzy Logic was implemented as a controller in this system to administer the flowrate of water, alkali and acid solutions into the soil in order to maintain its moisture and pH level. There are 2 memberships assigned as input fuzzy which are moisture and pH value while output have 3 memberships which are alkali, neutral and acid solution flowrate. The fuzzy rules were programmed into Arduino to control the water pump and valve opening. The system was able to store the data and display on mobile phone through Blynk mobile application. This system was tested on a chili plant where the growth of a plant under controlled environment have better performance compared to the traditional method.
