Abstract:
A sensor device includes a housing having a hole allowing substances to pass from an exterior of the housing to an interior of the housing, and a printed circuit board having a humidity sensor and at least one electronic component. The sensor device also includes a tube comprising a waterproof material, wherein a first end of the tube surrounds the humidity sensor, wherein a first seal is formed by between the first end of the tube and the printed circuit board, wherein a second end of the tube is located proximate the hole. The sensor device also includes a waterproof, breathable material layer disposed between the second end of the tube and the hole, wherein a second seal is formed between the material layer and the housing, wherein a third seal is formed between the material layer and the second end of the tube. The hole and the material layer allow water vapor to pass from the exterior to the humidity sensor. The first, second, and third seals prevent the water vapor from reaching the at least one electronic component.
