IOT POWERED WATER QUALITY MONITORING SYSTEM

Water quality monitoring is a critical necessity in modern environmental management, public health, and industrial water treatment operations. This paper presents the design and implementation of an IoT-powered water quality monitoring system that continuously measures key water parameters including pH, turbidity, and Total Dissolved Solids (TDS) using an ESP-32 microcontroller integrated with dedicated sensors. The system transmits real-time data to an IoT cloud platform, enabling remote monitoring and alert generation, while simultaneously displaying readings on an LCD for on-site observation. A Regulated Power Supply (RPS) ensures stable operation of all hardware components under varying load conditions. The proposed system provides a cost-effective, scalable, and automated solution for continuous water quality assessment, overcoming the limitations of traditional manual and laboratory-based testing methods.
