Development of an Affordable Water Quality Monitoring Device for Assessing Water Pollution in Natural Sources Using Arduino Uno Software

Water pollution has become a significant environmental challenge affecting human health, aquatic ecosystems, and sustainable development. Traditional water quality monitoring methods often require expensive laboratory equipment, trained personnel, and time-consuming procedures, making continuous monitoring difficult, especially in developing regions. This study focuses on the development of an affordable and portable water quality monitoring device using Arduino microcontroller technology for assessing pollution levels in natural water sources. The system integrates multiple sensors, including pH, turbidity, temperature, and Total Dissolved Solids (TDS) sensors, to provide real-time measurement of key water quality parameters. The Arduino Uno serves as the central processing unit, collecting data from the sensors and displaying results on an LCD screen. Experimental testing was conducted on samples collected from rivers, streams, and ponds. Results demonstrated that the device effectively measured water quality parameters with acceptable accuracy compared to standard laboratory instruments. The developed system offers a low-cost, user-friendly, and efficient solution for continuous water quality monitoring in resource-constrained environments. The study concludes that Arduino-based monitoring systems can significantly contribute to environmental protection and public health management.
