Claim:
1. A wind sensor having a housing and a wind detection element which is rotatably mounted on the housing and is formed by a wind wheel which has a cup-star having a plurality of cups, wherein at least one ohmic heating element is incorporated in the wind wheel and means are present for transferring energy between the housing and the ohmic heating element rotating with the wind wheel, which means comprise a primary coil arranged in the housing and a secondary coil arranged in the wind wheel, wherein the secondary coil is connected to the ohmic heating element, characterised in that the plurality of cups of the wind wheel are each mounted by way of flat webs, wherein the webs extend into the cups and divide the cups into two regions, and the at least one ohmic heating element is embedded in the webs and extends into the region of the cups, characterised in that there is present in the wind detection element at least one heating temperature sensor for detecting the temperature of the wind detection element and a secondary electronic control system, wherein the heating temperature sensor is connected to the secondary electronic control system for controlling the ohmic heating element in dependence on the temperature of the wind detection element, characterised in that a primary electronic control system for controlling the primary coil is provided in the housing and the primary electronic control system is connected to at least one housing temperature sensor, and characterised in that the at least one heating temperature sensor or the at least one housing temperature sensor or both the at least one heating temperature sensor and the at least one housing temperature sensor is a temperature-dependent resistor.
