Here's an implementation of an IoT-enabled home/office automation controller using an IoT-SDK.
Let us look at implementation of a simple IoT enabled home/office automation controller using the IoT-SDK which will provide the middleware that interfaces the industrial bus/protocol to the Cloud.
The system is realised using:
The IoT-SDK provides software components for both the gateway/device as well as the client. The cloud server interface in both the device as well as the client is well abstracted enabling seamless migration from one cloud platform to the other. The IoT-SDK supports Amazon Web Services (AWS) (https://aws.amazon.com/)cloud integration or open-source cloud server KAA implementation (http://www.kaaproject.org/overview).

Industrial gateway is the device that bridges the slow speed industrial serial buses & physical input/output with the TCP/IP realm. It is designed based on the AM437x processor system-on-chip (SoC) running Linux® and having the following sensor interconnect options:
The IoT-SDK will transform the system into an IoT enabled industrial gateway having the following capabilities:
The Cloud infrastructure is built using commercially available Amazon Web Services (AWS) or it can be hosted on custom IoT open source servers like KAA.
Client application provides the user interface to the IoT devices and its big data stored in the cloud server. The client application is developed using the IoT-SDK that provides APIs to abstract lower layers completely. All the business logic for interfacing with the cloud servers and interfacing with the IoT device (gateway) is abstracted with simple APIs. The APIs are available for:
The IoT is built on a confluence of technologies, including new and old hardware platforms, big data, cloud computing and machine-to-machine (M2M) computing with APIs bringing all of these parts together.
The AM437x processor SoC comes enhanced with 3D graphics acceleration for rich graphical user interfaces, as well as a coprocessor (the PRU-ICSS) for deterministic, real-time processing including industrial communication protocols, such as EtherCAT, PROFIBUS, EnDat, and others. This combined with feature-rich IoT SDKs available today, enables developers to rapidly build secure, enterprise-grade intelligent gateways catering to a wide range of applications beyond industrial and home automation like smart cities, connected cars, energy monitoring, fleet management, and health and wellness.
