Developing IoT Projects with ESP32

By: Vedat Ozan Oner

Overview of this book

Developing IoT Projects with ESP32 provides end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC. You'll learn how to employ ESP32 in your IoT projects by interfacing with different sensors and actuators using different types of serial protocols. This book will show you how some projects require immediate output for end-users, and cover different display technologies as well as examples of driving different types of displays. The book features a dedicated chapter on cybersecurity packed with hands-on examples. As you progress, you'll get to grips with BLE technologies and BLE mesh networking and work on a complete smart home project where all nodes communicate over a BLE mesh. Later chapters will show you how IoT requires cloud connectivity most of the time and remote access to smart devices. You'll also see how cloud platforms and third-party integrations enable endless possibilities for your end-users, such as insights with big data analytics and predictive maintenance to minimize costs. By the end of this book, you'll have developed the skills you need to start using ESP32 in your next wireless IoT project and meet the project's requirements by building effective, efficient, and secure solutions.

Summary

An IoT product is more effective and more valuable when it is integrated with other products and online services. In this chapter, we have learned how to integrate our ESP32 devices with Amazon AVS. This integration requires many steps to accomplish the task. We created a smart home skill and developed a Lambda function as the backend handler. AWS IoT Core was the glue between the ESP32 sensor and AVS. We created a device shadow on AWS IoT Core to hold the state of the ESP32 sensor. We have seen that all data exchanges are in the form of JSON documents and the document structures are available in the online Alexa documentation as the main reference. When we look at the products on the market, we can understand that voice interfaces are becoming more common among IoT products. Therefore, it is important for us to learn how to use voice services and integrate them within our solutions.

We have also experimented with IFTTT. It is an online rule engine, not only for IoT solutions...
