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.

Introduction to IoT for weather monitoring systems

A weather monitoring system senses the state of the atmosphere, such as its temperature, humidity, and weather conditions (clear, stormy, and so on). To get the state of the atmosphere, we need sensors.

We can design a simple model for an IoT weather monitoring system as shown next in Figure 2-2. An IoT board with sensor devices can sense physical conditions such as temperature and humidity. Some IoT weather monitoring systems can display their sensor values on a monitor or LCD display:

Now that we've discussed the weather monitoring system and its basic architecture, let's start building our weather monitoring system. In the next section, we'll learn how to read temperature and humidity using a sensor device and an ESP32 board.
