Gas Sensors - Technology and Applications

Many industrial and commercial activities involve the monitoring and control the environment, with applications ranging from domestic gas alarms, chemical warfare detectors and medical domestic apparatus to safety, environment, and chemical plant instrumentation. The largest barrier to achieve improved process or environment control often lies at the interface between the system and the environment to be monitored, i.e. the sensor. Without sensors, significant advances in control and instrumentation will not be possible. Hazardous and toxic gases from auto and industrial exhausts are the polluting the environment. In order to measure and control these gases, one should know the amount and nature of gases present in the environment. Thus the need to monitor and control these gases has led to research and development of wide variety of sensors using different materials and technologies. To increase the efficiency and capability of the instruments in measurement and detection technology, to reduce the cost, shape, size, weight etc,. This book is to understand basics of sensors, sensor technology, Mechanism, Choice of Materials and Need of Nanoscale Sensors.
