The invention relates to a hail sensor having an impact surface, on which precipitation can impinge, and at least one converter, which is arranged and formed in such a way that, in the event of a deflection of the impact surface as a result of precipitation striking the impact surface, the converter outputs a corresponding converter output signal. The impact surface is formed from wires or wire sections, cords or cord sections, or the like which are guided at at least approximately equal distances from one another and do not cross, which are each assigned a converter and which are arranged in such a way that, between the wires, cords, or the like, there is a distance through which liquid precipitation can easily pass after striking the impact surface.
