Infrared Sensor Application Note  2——————————download ：96264.pdf

INTRODUCTION
This document explains the signal processing required to linearise, temperature compensate and calibrate all SGX Sensortech
infrared gas sensors, followed by the calculations required to determine the concentration of the target gas.
External circuit/software will be required to perform the signal processing and to store calibration information (in non-volatile
memory). See Infrared Sensor Application Notes 3 and 4.
An example of each calculation is shown using typical values.
