摘要

The present invention relates to a white-cell type non-dispersive infrared gas sensor, and more specifically, to a non-dispersive infrared carbon dioxide gas sensor deposited with a hydrophobic thin film, capable of accurately measuring the concentration of a gas. To this end, in a carbon dioxide gas sensor for measuring the concentration of carbon dioxide included in a gas, the gas sensor is a white-cell type, first and second reflectors (120, 130) are disposed in a white cell to face a third reflector (140), a light source (110) is provided at one side of the third reflector (140), and a first detector (150) and a second detector (160) are provided at an opposite side of the reflector (140). In addition, a first hydrophobic thin film (122) is deposited on the entire reflective surface of the first reflector (120), a second hydrophobic thin film (132) is deposited on the entire reflective surface of the second reflector (130), and a third hydrophobic thin film (142) is deposited on the entire reflective surface of the third reflector (140).
