SMART WATER METER AND WATER QUALITY MONITORING USING IOT

The management of water quality and scarcity are major worldwide issues that call for effective, real-time monitoring systems. The design and implementation of an IoT-based Smart Water Meter and Water Quality Monitoring System that integrates sensors, GSM communication, and microcontroller-based data processing is reviewed in this paper. Key water quality parameters are measured by the system using Arduino Uno R3 as the central controller, which interfaces with water flow sensors (YF-S201), TDS (Total Dissolved Solids), turbidity, and pH sensors. A GSM module (SIM800L) wirelessly transmits the gathered data to a cloud server or mobile application, allowing for remote monitoring and the sending of alerts for contamination or excessive water use. For on-site observation, real-time readings are provided by a local LCD display.     The system ensures safe water quality by continuously monitoring contamination levels and improves water conservation by identifying leaks and unauthorized usage. Real-time analytics, automated reporting, and *low deployment costs are some of its main benefits, which make it appropriate for use in industrial, residential, and agricultural settings. Future advancements like machine learning-based anomaly detection and solar-powered operation are discussed, along with issues like sensor calibration, power consumption, and network reliability. This review emphasizes how IoT-based smart water systems can support public health and sustainable water management.
