Internet of Things is growing rapidly and billions of devices are connecting to the internet in different ways. One of the most necessary and important components of the future Internet of Things systems is an IoT gateway. An IoT gateway collects sensor data and communicates between protocols.
Sensors are the equivalent of our five senses for IoT but here instead of five senses, IoT systems may have hundreds of sensors with many of different functions such as measuring temperature, light, noise, the position of equipment, people tracking, weather readings, smart building operations, security alerts and more. IoT is not just about sensing or monitoring, it is also about controlling different systems such as turning the light on or off, HVAC and more through connected systems.
How IoT Gateway Intersects with Devices to the Cloud
All of your connected devices may not use single protocols to connect the internet or cloud, the devices may use different protocols such as Bluetooth, Wifi, BACnet, Ethernet, ZigBee, Modbus and others. Some sensors use very low energy like Bluetooth, and they can not connect to the internet directly. Some devices generate huge data that is uncontrollable and may not be valuable in its raw data.
An IoT gateway sounds very simple like a traditional gateway, but it is revolutionizing the connected world. It is able to connect devices that we could not connect before. IoT gateways are to perform many critical functions such as device connectivity, security, protocol translation, data filtering and more. The latest IoT gateway acts as platforms for application code which processes IoT data and becomes an intelligent part of an IoT ecosystem. IoT gateways positioned at the intersection of IoT system, connected devices or sensors, and the cloud.
Traditional gateways perform only protocol translation and few device management functions, they are not intelligent or programmable. Today’s new generation IoT gateways can deliver full-fledged performance, open up new opportunities, improve responsiveness and support new operating models. For example, an IoT building management system can control office and industrial space from a remote location using an IoT network of sensors and connected devices through the cloud.
Adding new smart IoT gateways can filter routine sensor data and perform their own analytic operations, which alert on the building temperature when it is too high, going even further, these IoT gateways can also take independent actions, such as turning on the AC. IoT gateways are appearing in three major industries, industrial automation, building automation and smart transportation. These intelligent IoT gateway solutions are rolling out to the present market, with the advantages of having full-fledged programmable capabilities and manageable platform.
We at BlueApp.io have the IoT gateway solution which connects Bluetooth Smart devices to the cloud over WiFi, BlueApp’s integrated IoT platform helps developers as well as customers to add remote connectivity features for their products. BlueApp.io’s platform along with our IoT gateway allows Bluetooth Smart nodes to be used in a smart home or building automation, industrial automation, lighting HVAC, retail, and many other environments.
