Water management is very important for ensuring that resources are used wisely in both urban and industrial areas. For industries to work smoothly, they need a steady and well-controlled supply of water. If water use is not regulated or if too much water is used, it can lead to inefficiencies and waste. To solve this problem, we propose a smart water flow monitoring system that constantly checks water usage and identifies if too much water is being used. The core of this system is a NodeMCU (ESP32) microcontroller, which is responsible for collecting data and controlling the system in real-time. The system uses a water flow sensor to measure the rate at which water flows through industrial pipelines. This sensor provides accurate and continuous data on how much water is being used. If the system detects that the water flow rate is higher than a set limit, it sends an alert to notify the appropriate people about the potential overuse of water.

To further prevent water waste, the system includes a solenoid valve. This valve automatically shuts off the water supply when it detects that too much water is flowing, helping to stop waste. The system also has a feature for monitoring water quality, ensuring that the water meets the necessary standards for industrial use.

The system is connected to an IoT-based mobile application, which allows users to access real-time data. Users can monitor water usage through the app, receive notifications about any issues, and even control the system remotely. This method not only helps industries use water more efficiently but also supports sustainable water management by reducing waste and ensuring water is supplied effectively. By combining real-time monitoring and Internet of Things (IoT) technology, this system provides a practical and scalable solution for managing industrial water use.
