The chemosensitive gas detection is one opportunity of low-cost and selective gas sensing. Absorption changes of the dye, due to the gas reaction can be detected in different ways, depending on the application and requirements. We give an overview of the state of the art of gasochromic sensing and of the different measurement principles. Following this, we describe our investigation on gasochromic materials for the detection of CO, NO2 and NH3.
