Abstract

With the development of economy and the intensification of human activities, the generation and emission of greenhouse gases are becoming more and more serious, which has a great impact on human society. In order to detect the concentration of CO₂, the main component of greenhouse gases, a photoacoustic spectrum gas detection system is designed by using infrared light source, photoacoustic cell and other equipment. By modulating the light source, the photoacoustic signal proportional to the gas concentration is obtained to measure the CO₂ gas concentration. The experimental results show that the detection system has stable performance and has good linear response characteristics, which can detect different concentrations of CO₂.
