Abstract	A multiple-gas sensor based on absorption spectroscopy technique using a super luminescent diode source of 1.5 μm is proposed and realized for combustion applications. This technique allows CH$_{4}$ and CO$_{2}$ gas sensing in bio-gas plant to monitor the quality of the gas. In this study, a solid Fabry–Perot etalon with a free spectral range of 517 GHz is also used and the detection limit is improved, allowing measurement with lower resolution spectrum analyzer. The detection limit of 292 ppm for C$_{2}$H$_{2}$ (at 1,543.7 nm), 4,492 ppm for CH$_{4}$ (at 1,525.92 nm) and 6.5 % for CO$_{2}$ (at 1,572.68 nm) is attained for 2 m path length with the spectrum analyser of 0.02 nm resolution. With the use of etalon, nearly the same detection limit is attained for all the species at 1 nm resolution.
