    Abstract: A fibre optic gas sensor and its manufacturing method are described. The fibre optic gas sensor consists of at least one optical fibre coated with a silica gel layer which changes its colour with a change in the concentration of gases, such as C0 2 , N0 2 , S0 2 , NH 3 and H 2 0, wherein the silica gel layer is applied on a stripped optical fibre surface and contains at least one indicator substance, such as phenol red or thymol blue, sensitive to a change of pH in the optical fibre working environment within a range from 0 to 14 and wherein the indicator substance is placed on a surface of treated optical fibre prepared in the process of tapering, etching, bending, or cutting. The manufacturing method of the fiber optic gas sensor consists of stripping an optical fibre, preferably a single-mode optical fiber, treating a visible section of the optical fibre and coating it with a chemically active substance, wherein the surface of the optical fibre is tapered, etched or cut and silica gel is the chemically active substance placed on the surface of treated section of optical fibre in an immersion process.
