摘要

Provided is a white-cell type non-dispersive infrared gas sensor and more particularly, a non-dispersive infrared carbon dioxide gas sensor deposited with a hydrophobic thin film. To this end, in a carbon dioxide gas sensor for measuring a concentration of carbon dioxide included in gas, the gas sensor is a white-cell type, in the white-cell, first and second reflectors (120) and (130) are disposed 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 the other side. Further, a first hydrophobic thin film (122) may be deposited on the entire reflection surface of the first reflector (120), a second hydrophobic thin film (132) may be deposited on the entire reflection surface of the second reflector (130), and a third hydrophobic thin film (142) may be deposited on the entire reflection surface of the third reflector (140).
