GAS SENSOR

A gas sensor is suitable for sensing a gas to be detected in an environment with humidity. The gas sensor includes an electrode unit and a sensing unit. The electrode unit comprises a first electrode layer and a second electrode layer, wherein the first electrode layer and the second electrode layer are arranged in a spaced mode. The sensing unit comprises an electric insulation sensing layer which is connected with the first electrode layer and the second electrode layer and is used for being in contact with the gas to be detected. The electrically insulating sensing layer includes a hygroscopic electrically insulating material. 一种气体感测器适用于在具有湿度的环境下感测待测气体。所述气体感测器包含电极单元及感测单元。所述电极单元包括第一电极层及与所述第一电极层相间隔设置的第二电极层。所述感测单元包括连接所述第一电极层及所述第二电极层且用来与所述待测气体接触的电绝缘感测层。所述电绝缘感测层包括吸湿电绝缘材料。
