Water Quality Monitoring System: Using Arduino Uno for pH and TDS Sensors

This paper presents a low-cost water quality monitoring system using an Arduino Uno microcontroller, which measures pH and TDS (Total Dissolved Solids) levels in real time. The system uses a pH sensor to assess the acidity or alkalinity of the water and a TDS sensor to measure dissolved solids. The data is displayed on an LCD screen, providing users with real-time information about water quality. This solution is suitable for applications in agriculture, industrial water treatment, and environmental monitoring. The project highlights the cost-effectiveness and practicality of using Arduino-based systems for water quality assessment, with potential for future improvements in sensor accuracy and remote monitoring features.
