This document discusses building an Internet of Things (IoT) application using IBM Bluemix, NodeRED, and simulated sensors. It provides examples of IoT devices like BB8 Sphero and Intel Edison and how IoT is currently used in smart homes, connected automobiles, healthcare, smart waste management, intelligent traffic monitoring, and agriculture. It then demonstrates building an app that gets data from a simulated sensor and draws a graph to analyze the data. The conclusion discusses building an app combining IoT with visual recognition by analyzing images from a Raspberry Pi camera.
