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.

Feature list of the multisensor

Most IoT projects start with a request coming from a business. The product manager in the project then tries to provide a list of features by analyzing the market, competitors, and requirements from the business to fulfill the business goals. Let's assume our product manager comes up with the following feature list for the multisensor:

  • The device can measure temperature, humidity, pressure, and ambient light level.
  • It has a display to show readings from the sensors. The display shows only one reading at a time.
  • Users can switch between sensors by using a rotary encoder.
  • A sound warning is generated for high and low temperature values.
  • The device sleeps to decrease energy usage when there is no-one around and wakes up when someone is detected.

As we now know the features, we can propose a solution for the project next.
