In this chapter, we gave tips on choosing hardware and a data exchange protocol for a prototype. We also described how to assemble a prototype with different sensors and build and run four types of applications, one for each of the protocols—HTTP, WebSocket, Modbus, and OPC UA. In addition, we overviewed the Predix services for storing, analyzing, and merging the sensor data from the prototypes.
In the next chapter, you will learn about data management techniques and their implementations for the IIoT stack.
