  Abstract

In this paper, a gas sensor module for detection of multi gas such as CO₂, CO and CH₄ is designed and fabricated using non-dispersive infrared(NDIR) technology. A small sized optical waveguide is designed by simulation of optimal optical path in the waveguide. In oder to increase optical path length, a diffusion mirror and a concentration mirror are designed, respectively. From the simulation results, five times reflections between two mirrors in the waveguide are obtained for optimum optical path length. A single IR source and four single-channel pyroelectric sensors are integrated in the optical waveguide. The gas sensor module consists of pulse driving circuit, pre-amp and LPF, including MCU for data processing and analysing. From measured results, the sensor module obtained 10.3 ppm standard deviation over 3,000ppm CO₂ concentration and 0.13% standard deviation over CH₄ 10% LEL at 20°C.
