Chapter 3 Design IoT Integration Design IoT is another fast-growing technology, which can assist you to build and implement a data gathering network to improve systems and establish a new channel for interaction. DXP is a platform that is capable of quickly adapting emerging technology to address major challenges. DXP is leading organizations toward innovation, which helps businesses with intelligence and advice. IoT systems use sensors to provide operational insights from the data. Intelligence is added by integrating the analytics and ML into IoT devices. The IoT is effectively connecting the digital world to the physical world. It helps to communicate and integrate information systems and the fields’ data, and it is possible to use this data in real time. The IoT is mainly divided into three layers as shown in Figure 3-23: physical sensing layer, IoT Integration layer (also called as middle layer), and IoT application layer. • Physical sensing layer: Physical sensing includes sensors, for example, temperature, proximity, pressure, etc.; and development boards also called prototyping boards to acquire data from the environment, like Arduino, Raspberry, Edison etc. Along with mobile phones and their sensors like microphone to get voice commands, proximity, accelerometer, and other sensors can be grouped as passive or active (passive sensors don’t require external power sources, whereas active sensors require external power to sense the external environment). Analog sensors produce a continues signal, whereas digital sensors produce a discrete signal. • IoT integration layer: The IoT integration layer integrates the data collected from a device to a NoSQL database along with a distributed computing platform like Apache Spark and Hadoop. Data acquired from sensors can be stored in the cloud and can be used later to create dashboards. The IoT integration layer is also called the middleware layer. This layer ensures security, quality of service (QOS), and provides IoT gateways as well. You can implement this layer in your DXP application by integrating IoT frameworks such as Iotivity, AllJoyn, Eclipse-Kura, etc. 93
