Abstract

This research presents a low-cost system for detecting microplastics in water using ultraviolet (UV) light and a photodiode sensor. The system utilizes fluorescence and light scattering properties of microplastic particles. An Arduino Uno processes the sensor data and displays results in real time on a 16x2 LCD. Experimental results show clear differences between clean and contaminated water, demonstrating the feasibility of this method for field-level detection.
