Overview of this book

The Internet of Things market increased a lot in the past few years and IoT development and its adoption have showed an upward trend. Analysis and predictions say that Enterprise IoT platforms are the future of IoT. AWS IoT is currently leading the market with its wide range of device support SDKs and versatile management console. This book initially introduces you to the IoT platforms, and how it makes our IoT development easy. It then covers the complete AWS IoT Suite and how it can be used to develop secure communication between internet-connected things such as sensors, actuators, embedded devices, smart applications, and so on. The book also covers the various modules of AWS: AWS Greengrass, AWS device SDKs, AWS IoT Platform, AWS Button, AWS Management consoles, AWS-related CLI, and API references, all with practical use cases. Near the end, the book supplies security-related best practices to make bi-directional communication more secure. When you've finished this book, you'll be up-and-running with the AWS IoT Suite, and building IoT projects.

Visualizing data from AWS IoT

In the previous section, we learned how to visualize data from the backend server that was built from Node.js. In this section, we will continue to work with data visualization. Now we will consume sensor data from AWS IoT. We will develop a simple project to consume sensor data from AWS IoT and then visualize it in the browser environment.

Our demo scenario can be described in the following figure. We develop the Node.js application that performs sensing of the physical environment, such as temperature and humidity. You can use a sensor device, such DHT11 and DHT22. For this demo, I will generate random values for the temperature sensor:

The sensor data will be sent to AWS IoT with the publisher/subscriber model approach. We can use AWS IoT SDK for JavaScript/Node.js to send data to AWS IoT on a specific topic channel.  Furthermore, we will implement a client application-based on web application. We will create a simple web application using HTML5 and JS to retrieve...
