Automatic pH and Humidity Control System for Hydroponics Using Fuzzy Logic

Hydroponics is a system of growing plants using water as the media without involving other planting media such as soil. Hydroponics becomes one of the options for people to grow crops with minimal land. Hydroponics requires sufficient care because the conditions needed by the plant cannot depend on the elements found in the soil like conventional farming in general but directly controlled by the system. The most important conditions for hydroponics are pH and humidity. To control the levels of these conditions, the proposed hydroponic system is built using water pumps, an exhaust fan, and sensors that can be monitored in real-time. In this research artificial intelligence, the fuzzy logic has been added into the system, hence it works automatically to provide pH and humidity needed by hydroponic plants.
