A SCADA system in IoT is a modern system that connects sensors, machines, and devices to a central control unit. It collects real-time data from various locations and processes it for better decision-making. In industries like water management, energy, and manufacturing, SCADA monitors conditions such as pressure, temperature, and flow. Through IoT integration, data is transmitted over the internet, making it accessible remotely. Operators can manage operations, detect issues, and adjust systems quickly. IoT enhances SCADA by providing automation and reducing manual intervention.
