Gas Sensor Technologies for Environmental Sensing

This book presents the most common, basic gas sensing technologies and their respective potential against the background of user requirements. Aimed at providing a signpost to end-users with regard to the gas sensing technology that is suitable for different measurement scenarios it starts with a concise summary of the basic working principles that are commonly used in gas sensing. Based on this the potential of these technologies with respect to selectivity, sensitivity, stability, and the potential for miniaturization is discussed. In particular, the book shall focus on techniques that allow for gathering reliable information about the composition of gaseous samples and includes examples of applications and a discussion as to why a specific technology is used in these situations. Key Features:. Concise yet comprehensive introduction to gas sensing technologies. Reader is put into a position that allows him to evaluate technological offers/alternatives. The book will enable end-users to decide which technologies are worth developing further for a given scenario. Miniaturized gas sensing will play an ever more important role in the future of medical devices, large scale environmental monitoring, IoT, and consumable industry. The book provides a starting point to explore the possibilities of chemical sensing. The book will focus on the strengths and weaknesses of the different gas sensing approaches, which often fundamentally limit their potential.
