Study of the Gas Sensor Precision Based on Leastsquare Method

LU Fengjie Zhang Yongrui Yang Gang(School of Electro-Mechanical Engineering,Xidian University,Xi'an 710071,China)  
The latest research into the gas sensor's calibration models and methods is introduced.Since traditional models and methods fail to meet the data precise requirement in the modem science,a scheme with better efficiency and lower error for improving calibration is needed.In this paper,the technique of the virtual instrument and the method of leastsquare is proposed,which can largely improve the measurement precision of the gas sensors.
