This book contains 20 papers devoted to the domestic use of sensors. This up-to-date review fills a gap in the literature arising from the recent intense research and development of these sensors and takes an interdisciplinary approach to the operation principles of sensors and the preparation techniques, with particular regard to microelectronics techniques which allow the realization of sensor systems with integrated electronic circuitry.The applications of sensors in the domestic environment are accurately reviewed and the trends of future sensor development are also outlined.
