When air quality needs to be detected, the infrared pyroelectric sensor rotates to the air detection module, as shown in fig. 1. The controller adjusts the output wavelength of the infrared light source 30 and the wavelength range filtered by the filter assembly according to the type of air to be detected, thereby evaluating the composition and concentration of the gas according to the absorption condition of each characteristic wavelength. For example, the characteristic absorption wavelength of common carbon dioxide is 4.26 μm, that is, carbon dioxide has a strong absorption effect on infrared energy of 4.26 μm, and the composition and content of carbon dioxide can be evaluated according to the absorption condition of the wavelength. Since the wavelength range of 3.96 μm is the non-active region of carbon dioxide and infrared radiation, in order to ensure the accuracy of the test, the wavelength is used as the reference detection wavelength to eliminate the influence of factors such as system environment.
