ArduFarmBot: Tomato garden automation with help of “Internet of Things” – IoT ( MJRoBot Tutorials Book 1)

This book uses the electronic controller “ArduFarmBot” as a basis for learning how to work in both HW and SW, with: a) LCD and OLED type displays; b) LEDs and buttons; c) Activation of pumps and lamps via relays and d) Sensors such as: DHT22 (temperature and relative air humidity), DS18B20 (soil temperature), YL69 (soil moisture) and LDR (luminosity).

All key stages of the project are documented in detail through explanatory texts, block diagrams, high-resolution color photos, electrical diagrams using “Fritzing” application, complete codes stored in “GitHub” and “YouTube” videos.

Two versions of the electronic controller “ArduFarmBot” are developed in detail in this book. From capture of data coming from a garden, such as air and soil temperature, relative humidity, soil moisture and luminosity, the “ArduFarmBot” helps to control when a crop should receive heat and water. Control will happen automatically, locally and remote via internet.

The book is divided into 3 parts.

In the first part, the Arduino Nano is the starting point for development of a local version of “ArduFarmBot”, that can be controlled both, manually and automatically.

In the second part, the book dives into automation design, introducing remote operation through the creation of a webpage. The “ESP8266-01” is used for Wi-Fi connection, sending data to an important web service in the field of IoT, the “ThingSpeak.com”.

In the third part, a second version of “ArduFarmBot” is developed, introducing the “NodeMCU ESP8266-12E”, a powerful and versatile IoT device, which replaces both the “Arduino Nano” and the “ESP8266-01”, used in the earlier parts of the book. In this last part of the book, a new and powerful service platform of the IoT universe, the “Blynk”, is also explored.
