Internet of Things Projects with ESP32

By: Agus Kurniawan

Overview of this book

ESP32 is a low-cost MCU with integrated Wi-Fi and BLE. Various modules and development boards-based on ESP32 are available for building IoT applications easily. Wi-Fi and BLE are a common network stack in the Internet of Things application. These network modules can leverage your business and projects needs for cost-effective benefits. This book will serve as a fundamental guide for developing an ESP32 program. We will start with GPIO programming involving some sensor devices. Then we will study ESP32 development by building a number of IoT projects, such as weather stations, sensor loggers, smart homes, Wi-Fi cams and Wi-Fi wardriving. Lastly, we will enable ESP32 boards to execute interactions with mobile applications and cloud servers such as AWS. By the end of this book, you will be up and running with various IoT project-based ESP32 chip.

Making Visual Data and Animation on an LCD

The ESP32 chip and module consists of general-purpose input/output (GPIO) pins to enable sensing and actuating. In this chapter, we will learn how to read sensor data from the ESP32 GPIO. We will also talk about using an LCD to display data with the ESP32 chip. In addition to this, we will show sensory information such as temperature and humidity in the LCD. Ultimately, we will build a simple IoT weather monitoring system with the ESP32 board.

We will see how to work with an LCD by following step-by-step instructions. You will also learn how to use the ESP32 board to detect the weather and display it on LCD by the end of this chapter.

The following topics will be covered in this chapter:

  • Introduction to ESP32 GPIO
  • Introduction to IoT for weather monitoring systems
  • Reading temperature and humidity from a sensor device
  • Displaying information...
