Anti-freezing wind direction sensor

The invention provides an anti-freezing wind direction sensor; the anti-freezing wind direction sensor comprises a shell, a wind direction support rotatably arranged on a body frame, and a wind detection element arranged on the wind direction support, and further comprises a waterproof eave which is arranged along the lower edge of the wind direction support, and the waterproof eave surrounds thepart of the shell in a surrounding manner; a gap space is formed between the inner side wall of the waterproof eave and the outer side wall of the shell; and a first heating element is arranged in thegap space. The waterproof eave is arranged at the part, matched with the wind direction support, of the shell, and the waterproof eave can guide the melted water drops to be discharged to the outside, the problem that water drops formed after melting can easily enter the inside of the sensor, and the use of an internal coil and a circuit board is affected is solved. Further, the first heating element is arranged in the ga
