Fuzzy Controlled LED Lighting Compensation for Aeroponics System

Solar is one of the primary sources of light energy for plants, and it is significant to its energy conversion process – photosynthesis. Due to some unpreventable factors and restricted locations, plants do not constantly receive their needed energy, affecting the crops. With technological advancements, artificial lightings are integrated into agricultural systems to compensate for this lack of supply. The given aeroponics system uses two different spectra of light-emitting diodes (LED) – white and an equal combination of red and blue – as lighting compensation. These artificial lights are controlled by fuzzy logic, which treats the lux value as the input and the brightness as the output. On this setup, having a p-value of 0.0006 compared to 0.1592, the blue and red-light compensation creates a significant improvement. The same is for the number of leaves, with the blue and red having a value of 0.0398 and white with 0.1828. Lastly, the identical light spectra created the most prominent gap with the weight reading 6.25g. The combination of red and blue had proven a better effect than white and regular sunlight concerning the plants’ height, weight, and the number of leaves.
