Arduino Remote Sensing & Control Using 433 MHZ Modules

This book introduces you to remote sensing and control projects using the Arduino Uno and the 433 MHz transmitter/receiver (Tx / Rx) modules. We have been quite specific in our coverage in an attempt to thoroughly explore the subject with particular reference to a pair of readily available and inexpensive remote control modules. These modules have a good transmission range and are simple to use - particularly with the library that we have created to simplify the sending and receiving of data.
Assumed Level of Previous Knowledge

While this book is intended to be an informative source for a broad range of experimenters, it has been written with a narrow focus on a particular topic (remote sensing and control) using a particular resource (the 433 MHz modules). We expect that the reader will have conducted at least a few basic Arduino experiments and will have gained some familiarity with the programming language. We provide program notes for most experiments where we attempt to outline the purpose and working of the code. While we don't explain the program code in every detail, the programs are internally documented to indicate the purpose of relevant lines of code.
Why We Have Created this Book and How it Teaches You
There were two main thoughts behind this book: to investigate various remote control projects, and to do this with reference to a specific component through a series of related projects each involving a short set of experiments in which the user could gradually build up their knowledge and that additional programming code could be introduced in a readily understandable way. We wanted the reader to feel that having completed the book, they would be confident in setting up any project using these modules.
