An IoT gateway is a smart device that connects IoT sensors and devices to the cloud. It collects data from multiple sources, filters it, and sends only useful information for further processing. Gateways act as the bridge between local networks and the internet. They also enhance security by encrypting data before transmission. These devices support various protocols like MQTT, HTTP, and CoAP, making them essential in smart systems. Whether used in agriculture, water monitoring, or manufacturing, IoT gateways ensure smooth, reliable communication.
