Abstract

In a device and method for sensing condensation conditions and for removing such condensation from a surface (1), a first thermal sensor (2) is in thermally conductive contact with the surface (1). A second thermal sensor (6) is in thermally conductive contact with a cooling device (8). A circuit (20) activates the cooling device in order to maintain the second thermal sensor (6) at a temperature that is lower than a temperature of the first thermal sensor. A humidity sensor (13) is in thermally conductive contact with the cooling device. A circuit causes a condensation removal mechanism to be activated for removing liquid from the surface when the humidity sensor indicates a presence of condensation at the temperature that is lower than the temperature of the first thermal sensor.
