First of all, I must say thanks to my acquisition editor Richard Harvey. I never knew that I could write a book on such an amazing topic as Raspberry Pi Sensors. He gave me the opportunity and tremendous support and motivation before I wrote the initial chapters. So thanks for selecting me out of millions as the author of this book and inspiring me to do this.

Thanks goes also to my content editors Natasha Dsouza and Owen Roberts. You were always ready to lend me a hand wherever I was stuck. Thanks for the understanding and cooperation when I lost my pace of writing in the intermediate chapters due to tremendous work pressure. Special thanks to Natasha, who has poured hours of her time to edit the content and make it better, and supported me throughout the time I spent writing this book.

Then, thanks to my technical content developers David Alcoba, Siddharth Bhave, and Cédric Verstraeten. I sincerely thank you for investing your precious time technically reviewing this book, and providing very useful additions and valuable comments over the content, to make it more interesting for readers. By incorporating your valuable suggestions, this book has achieved a really good shape.

How can I forget Shiny Poojary and team who edited the book technically and filtered out errors in the content of the book. They totally changed the presentation of the book. I thank her for her continuous support, working untiringly to edit the book on time, and taking it to the final stage. I also thank all the employees of Packt Publishing who were directly or indirectly involved in this project, for managing everything and delivering it to the readers' hands.

Thanks to my friends, professors, and colleagues. I would like to thank all my friends, who have been part of my life, given me happiness, supported me to do this, and wished me the best before I started working on this book. Thanks to the professors at VIT University, and special thanks to Dr. Arun Manoharan for giving me a small but very helpful insight into being an author. My colleagues at Leaf Technologies always took updates from me about the progress of this book and encouraged me to include strong content.

Above all, I would sincerely like to thank my parents for asking me every day about this book's progress and showing keen interest in seeing it take shape, in spite of all the time for which it kept me away from them.
