Illuminance performance of the solar sharing smart LED lighting for indoor vertical farming using fuzzy logic controller

The solar sharing smart LED lighting system based on the fuzzy logic application that automatically adjusts the LED lighting appropriate for indoor vertical farming specifically on high-valued crops like lettuce (Lactuca sativa). The concept of this study is to make a smart LED lighting system more economical using Arduino and power-efficient by using renewable energy like solar power. This study aims to determine the illuminance of the sun that can adopt the natural light intensity for indoor farming. Hence, smart LED lighting will be developed to automatically adjust the light intensity needed by the plants to grow indoor using a hydroponics system by means of Arduino. The fuzzy-controlled system fuzzy set is made of three categories: high intensity, moderate intensity and low intensity settings It also provides the needed light for photosynthesis in different growing stages. A fuzzy logic controller controls the entire system when to light's up and dims down the LEDs that ensures the intended output was achieved. The system was tested and measure its illuminance performance with 96% success rate.
