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.

Automated gardening controller

M2M forms the basis for elaborate control systems that involve monitoring remote sensors. To demonstrate that, we will build an automated gardening controller using M2M. This will involve monitoring the soil moisture and temperature of a garden, and controlling a water pump and a ventilation system.

Getting ready

You will need the following hardware components for this project:

The first setup will be the sensor hub, which will comprise of an ESP8266 board, a soil moisture sensor, and a DHT11 sensor. Connect a 10 kΩ pull up resistor to the DHT11 data pin, and connect the VCC pin and GND pin of the sensor...
