Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Monitoring several ESP8266 modules at once

In advanced and more complex monitoring solutions, you will have to use several ESP8266 modules. This may be due to the distance between the areas where parameters are being monitored, or when the sensors being read are more than the number of GPIO pins available on an ESP8266 module. In such cases, you will have to monitor data from more than one ESP8266 module on the same dashboard. To demonstrate how to do that, we will use one ESP8266 board to monitor temperature and humidity with the DHT11 sensor, and another ESP8266 board to monitor soil moisture. Data from both ESP8266 boards will be monitored using one dashboard.

Getting ready

You will need these hardware components:

Start by mounting the ESP8266 board and the DHT11 sensor onto the breadboard...
