Abstract

This paper introduces the application of Lamber-Beer´s law to the concentration detection technology of infrared gas, and describes its working principle and characters of various important components. This paper focuses on the design of light source, sensor, signal acquisition and signal processing circuit. Through the analysis of its actual work process, the feasibility of the design is verified. In this paper, the advantages of infrared gas concentration detection are analyzed and the development direction in the future is also discussed.
