摘要

In the science and industry fields, Non-dispersive Infrared (NDIR) gas Detection Technique is usually used to measure the concentration of carbon dioxin (CO2). NDIR is an accurate and stable technique for analysing gas concentration and to be used in running automatic monitor system or longterm stable measurement. So far, it usually require 5 to 15 minutes to activate the circuit system until it is ready for measuring and the light source would be able to produce a stable spectrum infrared radiation. This research will use Correlated Double Sampling to adjust timing and shading value for analysing, which can improve not only the slow wait time effectively, but also the practicability of NDIR measurement substantially. The detector that design for the research required 28 seconds to activate and the effective loading time for measurement takes 37.5 seconds which is shorten about 23times of effective loading time with 865.5 seconds as the standard CO2 detectors do.
