Abstract: A humidity sensor having a housing, a data logger that has such a humidity sensor as well as a evaluation method for the humidity sensor or the data logger. The housing of the humidity sensor has a recess in which a humidity sensor element is situated. To protect the humidity sensor element against the ingress of water, a membrane is provided that covers at least a portion of the recess and thus defines a detection volume around the humidity sensor element. This membrane allows for an exchange of air with the surroundings so that the humidity sensor element is able to detect the air humidity. It is also designed in such a way that it prevents the ingress of water. The detection volume is designed to be as small so that the humidity of the detection volume adapts quickly to the surrounding climate that is to be measured.

Abstract: A composite insert has at least one metallic contact element which is extrusion-coated with the aid of a premolded part which has a first three-dimensional sealing surface to an injection mold, a stiffener of the contact element being formed beyond a transition region of the premolded part to the injection mold.
