Abstract: A optic fiber gas sensor system,which is a type of all-optics and naturally safe is described.It detects the gas density in air,suing the mixture absorbing band of gas in 1.33μm,according to the lambert law and twowavelength difference absorbing method.It also uses the microcomputer to collect and process data.The precision can reach 0.025%.
