An electric or electronic device module comprises an electronic device, means for powering the electric or electronic device module, and at least one radar sensor having a detection range. The electric or electronic device module has a processor adapted for calibrating the at least one radar sensor by at least partly automatically defining and calculating parameters of boundaries of a predefined geometry, in which the at least one radar sensor has to measure, in order to prevent the at least one radar sensor from taking into account measurements outside that predefined geometry. The predefined geometry is located within the detection range of the at least one radar sensor and is equally sized to or smaller than that detection range of the at least one radar sensor.
