From a general point of view, a chemical sensor is a device capable of continuously monitoring the concentration of an analyte. The two main classes are electrochemical sensors and optical chemical sensors. The latter are based on the measurement of changes in an optical quantity refractive index, light scattering, reflectance, absorbance, fluorescence, chemiluminescence, etc. For remote sensing, an optical fiber is used, and the optical sensor is then called an optode because of... 

It is often necessary to monitor for gas leaks inside the gas cabinet or in the surrounding area. Sensors to monitor semiconductor gases are available based on a number of different technologies. Some of the types include solid state sensors, electrochemical sensors, and paper tape sensors that draw a sample from the sensing area to a remote location to react with chemicals on the tape. No one type of sensor is ideal for all types of gases. Gas detection is explained more fully in a separate section.
