subject: Role of IoT Gateway in Smart Water Management [print this page]
An IoT gateway is a device that connects IoT sensors, controllers, or machines to the internet or cloud platforms. It works like a bridge between your physical devices and software applications. These gateways collect data from various devices using local protocols like Zigbee, Bluetooth, or Modbus. They then convert this data into internet-friendly protocols such as MQTT or HTTP.
Beyond just connecting devices, an IoT gateway can filter, process, and encrypt data before sending it to the cloud. This helps reduce unnecessary data traffic and boosts security. It can also perform some tasks locally when internet connectivity is low—this is called edge computing. In simple terms, IoT gateways allow seamless communication and control between devices and cloud services, making them a critical part of any IoT ecosystem, especially in applications like smart water systems, industrial monitoring, and smart city infrastructure.
