Many of these devices weren’t originally created with Internet capabilities and must be modified with after-market solutions to become connected. As an example, the following graphic shows the connectivity between an industrial tank sensor using a Digi XBee® radio module, communicating with a gateway that houses a Digi ConnectCore® System on Module (SOM). Typically, we’re focused on devices with a narrower purpose, such as controlling the lights in your home or tracking tank levels for manufacturing chemicals. While an IoT device is arguably any electronic device that can communicate with the Internet, we usually don’t mean mobile phones or general use computers. When we talk about IoT devices, we are usually describing things like environmental sensors, connected appliances, vehicle trackers, or even assembly line machines. User interface – where people see IoT information, manipulate it, and issue commands back to IoT devices.

Cloud applications – process IoT data into useful information, for presentation to users.

Network servers – systems that manage the acceptance and transmission of IoT data, typically located inside cloud data centers.Gateways – translate and re-transmit information, typically linking local device networks to the Internet.Application protocol – the framework that defines how information content is transported.Local communications – the method the device uses to speak with neighboring devices.IoT device – anything from the tiniest temperature sensor to a giant industrial robot.While IoT systems come in many different architectures, most include the following components: What's the device’s power budget? What are the cost limitations? What are the requirements for physical size, security, time to market, geographic regions and remote maintenance? In this article we'll take a look the embedded components of an IoT communication system, and discuss how different needs and contexts determine the best solution for each use case. There are also constraints to be considered. The right choice always depends on the application’s specific needs. There’s no single best protocol, which is essentially the common 'language' used to route messages from one IoT device to another. That's because how they communicate depends on what they are, where they are, what other devices and systems they need to talk to, and what they have to say.
