The present invention relates to a gas sensor module for detecting gas concentration in air capable of securing enough required light paths and simultaneously detecting various harmful gases. The gas sensor module of the present invention comprises: a gas detection unit including a light source; a light chamber providing a light path; a light cable installed on the other side of the light chamber, collecting light of the light source to provide to a light sensor; and the light sensor installed on the other end of the light cable. Moreover, the light source is installed on one side of the light chamber and the light chamber according to the present invention comprises: a first through hole having the light source installed therein; a planar mirror reflecting the light emitted from the light source; a curved mirror re-reflecting and collecting the light; and a second through hole receiving the light collected by the curved mirror, having the light cable inserted therein, wherein a first protrusion is installed between the first through hole and the curved mirror and a second protrusion is installed between the planar mirror and the second through hole. |
