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.

Mapping Wi-Fi hotspots to Google Maps

If we store our Wi-Fi SSIDs and GPS location in external storage such as a microSD card, we map the Wi-Fi hotspot into Google Maps. You can view Google Maps at After logging into Google Maps, you can see the web form in Figure 7.9:

Figure 7.9: Creating your own map with Google maps

To create a new private map, you can click on the CREATE A NEW MAP button; you will then see something similar to Figure 7.10.

Now you can upload a CVS file that consists of a Wi-Fi SSID and its locations. You should see your Wi-Fi SSID names on the map:

You can experiment with what we have learned here in your own time. I recommend looking at an example of the Wardriving project at
