Smart water meters are digital devices that measure water usage in real time and transmit the data remotely. Unlike traditional meters, they provide accurate and instant readings without manual intervention. These meters help both utilities and consumers track consumption, detect leaks, and reduce wastage. Smart water meters use wireless communication to send data to central systems, improving billing accuracy. They support sustainable water management by encouraging responsible usage. With the rise of smart cities, smart water meters are becoming an essential part of digital infrastructure. They offer transparency, efficiency, and better control over water consumption. From homes to industries, smart water meters are transforming how we use water.
