An IoT gateway is a device that connects IoT sensors and devices to the cloud or central server. It collects, processes, and transmits data from multiple devices securely and efficiently. Without an IoT gateway, devices would need to connect directly to the cloud, which is costly and unreliable for large-scale operations. Gateways support different protocols, handle local processing, and improve system performance. They are crucial for smart applications in industries, agriculture, and water systems.
