Monitoring water levels in reservoirs, tanks, and rivers requires accurate and timely data. An IoT gateway connects sensors deployed in water sources and transmits real-time data to cloud-based platforms. This helps industries, municipalities, and agricultural sectors make informed decisions regarding water usage. The IoT gateway ensures stable connectivity, even in remote locations, using cellular, Wi-Fi, or LPWAN technologies. It enables predictive analytics by detecting unusual level fluctuations, preventing overflow or shortages. By integrating with SCADA systems, an IoT gateway ensures automated control of pumps and valves, optimizing water distribution and conservation.
