11.1  Signal Processing

A sensor system has become very important to make us aware about our surroundings and to provide security and surveillance in respect of both our health and environment, whatever may be the type of sensor. Signal-conditioning unit is an essential part of a gas sensor system as otherwise it is not possible to convey the information to the common people. Especially field engineers are mostly benefited as they have to move in hazardous environments at any point in time. This unit not only detects but also determines the concentration level of a particular gas. In coal mines application, it can include an additional feature of safety and bring the reliability. Where the system is highly automated, ...
