Detection unit for gas sensor, gas sensor, system for detecting a plurality of different target gases, and method for detecting a target gas

Abstract

A detection unit for a gas sensor, having at least one gas-sensitive element (1) including at least one gas-sensitive material, the optical properties of which vary as a function of the contact with a target gas. The detection unit is configured for arrangement on a mobile evaluation unit (5) having an image acquisition unit (6), in order to form a gas sensor, and the detection unit has at least one optical lens (2), and the gas-sensitive element (1) and the optical lens (2) are arranged in such a way that the ambient light (U) that passes through the gas-sensitive element (1) can be imaged by the optical lens (2), in particular can be imaged onto the image acquisition unit (6) when the detection unit is arranged on the mobile evaluation unit (5).
