| Abstract: | Based on absorption spectrum of CO2 and Beer-Lambert law, a kind of infrared absorption CO2 gas sensor which is easy to realize is designed. Through single beam and dual wavelength infrared measuring method, which is not divergent, high accuracy and high selectivity detecting of CO2 is realized. The sensor has many characteristics such as simple structure, small size, stable performance and high anti-jamming. It is possessed of wide application area. |
