Title (EN) GAS SENSOR
(FR) CAPTEUR DE GAZ
(KO) 가스 센서
Abstract:
(EN) The present invention relates to a gas sensor that minimizes the effects of humidity. Provided, in the present invention, is a gas sensor comprising: a substrate; a unit sensing unit disposed on the substrate and including a wiring electrode, a heater electrode, and a gas sensing material; a protective cap having a side wall part formed on the substrate and surrounding the unit sensing unit and a cover part disposed above the unit sensing unit and including at least one hole; and a heater unit disposed between the unit sensing unit and the cover unit, wherein the heater unit generates heat together with the heater electrode so as to lower humidity around the unit sensing unit.
(FR) La présente invention concerne un capteur de gaz permettant de réduire au minimum les effets de l'humidité. La présente invention concerne plus précisément un capteur de gaz comprenant : un substrat ; une unité de détection d'unité disposée sur le substrat et comprenant une électrode de câblage, une électrode de chauffage et un matériau de détection de gaz ; un capuchon de protection possédant une partie de paroi latérale formée sur le substrat et entourant l'unité de détection d'unité et une partie de couvercle disposée au-dessus de l'unité de détection d'unité et comprenant au moins un trou ; et une unité de chauffage disposée entre l'unité de détection d'unité et l'unité de couvercle, l'unité de chauffage générant de la chaleur conjointement avec l'électrode de chauffage de façon à abaisser l'humidité autour de l'unité de détection d'unité.
(KO) 본 발명은 습도 영향성을 최소화 하는 가스 센서에 관한 것이다. 본 발명은 기판, 상기 기판 상에 배치되고, 배선 전극, 히터 전극 및 가스 감지 물질을 구비하는 단위 센싱 유닛, 상기 기판 위에 형성되어 상기 단위 센싱 유닛을 에워싸는 측벽부 및 상기 단위 센싱 유닛의 상측에 배치되며 적어도 하나의 홀을 포함하는 덮개부를 구비하는 보호 캡 및 상기 단위 센싱 유닛과 상기 덮개부 사이에 배치되는 히터부를 포함하고, 상기 히터부는 상기 단위 센싱 유닛 주변의 습도를 낮추도록, 상기 히터 전극과 함께 발열되는 것을 특징으로 하는 가스 센서를 제공한다.
