Summary:This research deals with the CO2/CO Dual Sensor Module measuring CO2 and CO, that is the representative environmental harmful material, simultaneously. In the measurement of the CO2 and CO generally, the Non-Dispersive InfraRed method(NDIR method) is used for the precise measurement and durability. This method is to measure the concentration of the gas by using the Lambert-beer rule. When measuring the gas density with the NDIR method, the important factor is the apparatus for being called an optical chamber consisting of the emitter sensor and detector sensor are used for measuring concentration of the gas. Thus, this paper introduces an optical chamber of the new way of using the NDIR method and through this, shows an experimental result of the CO2 gas concentration measurement and it presents possibility for measurement of the concentration of the CO.
