Abstract: A temperature sensor device for sensing a temperature of a surface of an object includes a temperature sensor element being or comprising a thermistor and a housing having a measuring cavity in which the temperature sensor element is disposed. The housing has a measuring surface contacting the surface of the object, an outer shell, an inner shell, and an outer cavity formed between the outer shell and the inner shell. The outer shell, the inner shell, and the outer cavity thermally insulate the measuring cavity and the measuring surface from an environment of the object.
