Low-Cost Optical Detection of Microplastics in Water Using UV-Induced Fluorescence and Photodiode Sensing
AI summary Read the abstract
Researchers built a low-cost microplastic detection system pairing UV light with a photodiode sensor and Arduino-driven LCD readout, demonstrating that fluorescence and light-scattering differences between clean and contaminated water samples are sufficient to detect microplastics in the field without laboratory equipment.
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.
