It is indubitably established verity that sensors revitalize the everyday life of a human being. The sensor technology in itself is a multidisciplinary and the researchers are striving hard to develop the smart sensors. The emerging ASICs their semicustom counterparts and the microcontroller based sensor interfaces are the pathways towards realizing the smart sensors. In this book, the authors have dealt with the microcontroller based sensor interfaces in depth. Exclusively written for the budding researchers in this field, the book presents know-how as regards to the various sensor interfacing techniques to microcontroller. The coverage is well supported by means of appropriate pseudo code, 'C' based code and so on. Authors have also referred the prior art from various research journals, web URLs and the same is placed for the benefit of the potential readers. The interfacing diagrams are meant for a generic microcontroller paradigm and needs customization when intended to be implemented in real life. The book is apt for the entire Electronics and sensor fraternity and is all set to arouse the interest of the researchers in this area of ever-increasing technological importance.
