Smart water management using IoT is an innovative approach that integrates Internet of Things (IoT) technologies to monitor, control, and optimize water usage in real time. By using smart sensors, automated data collection, cloud computing, and intelligent analytics, smart water management using IoT helps detect leaks, reduce wastage, improve distribution efficiency, and ensure sustainable water resource management for cities, industries, and agriculture. This system supports better decision-making, cost savings, environmental protection, and long-term water conservation.
