| Summary: | 碩士 === 國立勤益科技大學 === 電子工程系 === 103 === Fires are difficult to avoid, so if fast or immediately fled the scene of the fire the fire scene for emergency fire fighting process, to increase the chances of survival of the people and reduce the loss of finance. Occurred during each field of fire, will go through growing, exuberant and recession of the flame, therefore certain combustible substance has a close relationship. And the vast majority of the combustible substances, both containing carbon (C), hydrogen (H) element, because in the combustion process, the carbon, hydrogen and oxygen (O2) do engage, will produce products of incomplete combustion, such as carbon dioxide ( CO2), and incomplete combustion products such as carbon monoxide (CO) and other toxic gases. It can be seen, carbon dioxide and carbon monoxide during combustion flame is the material inevitably produce, so if in front of flame into the strong (the fire), the use of modern gas sensor technology (Nondispersive Infrared Detector, NDIR) for carbon dioxide and go carbon monoxide do synchronous analysis possibilities warning fires, and then with, under the concept of modern society to have one, and make the most rapid notified via App of the system, so that people make an immediate response to avoid greater losses .
