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.

Technical requirements

As hardware, we only need an ESP32 devkit and a DHT11 sensor.

You can find the code for the chapter examples at this link: https://github.com/PacktPublishing/Internet-of-Things-with-ESP32/tree/main/ch10.

The common libraries are located here: https://github.com/PacktPublishing/Internet-of-Things-with-ESP32/tree/main/common.

We need a new external library while developing the AWS example, which can be cloned from this repository: https://github.com/espressif/esp-aws-iot.git.

An AWS account and an Identity and Access Management (IAM) user are required. This documentation explains how to do that if you don't have an AWS account: https://docs.aws.amazon.com/polly/latest/dg/setting-up.html.

Eclipse Mosquitto is the MQTT message broker that we will use in this chapter. It also provides the client applications to connect to any message broker. This page helps with the installation: https://mosquitto.org/download/.

In the CoAP server example, we...
