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 sensor data from a cloud dashboard

In this recipe, we will be looking at how to use a graphical interface to monitor the data logged by the ESP8266. One of the main reasons why sensor data is posted online is so that you can easily monitor the data over time. This is facilitated by cloud dashboards that take the posted data and convert it to meaningful graphical presentations. The graphical presentations guide us in the decisions and actions we take pertaining to the system that is being monitored. We will use and to demonstrate how cloud dashboards work.

Getting ready

Set up the hardware the same way you did in the, Connecting sensors to your ESP8266 board ercipe and upload the code for posting sensor data to


That is the code we used in the, Posting the sensor data online recipe.

No configuration will be required in for you to get a graphical view of the posted data. On the other hand, you will need to set up a few things in freeboard...
