The increasing demand for clean and safe water has become a major concern in both industrial and environmental sectors. Traditional methods of water quality analysis are time-consuming and require laboratory testing, which makes real-time monitoring difficult. To overcome this issue, a real-time water quality monitoring system is proposed using Arduino and ESP8266. The system continuously measures important water parameters such as pH, turbidity, total dissolved solids (TDS), temperature, and water level using various sensors. A water level sensor ensures that measurements are taken only when water is present, improving system reliability. Additionally, a GPS module is integrated to provide the exact geographical location of the monitoring device, making it suitable for deployment in rivers and industrial environments. The Arduino microcontroller processes all sensor data and displays the readings on a 16×2 I2C LCD for local monitoring. Furthermore, the data is transmitted to the ESP8266 Wi-Fi module, which sends the information to a cloud-based platform for real-time monitoring through a web dashboard. This system provides an efficient, low-cost, and scalable solution for continuous water quality assessment. The proposed approach helps in better decision-making and ensures timely detection of water contamination.
