Wind direction sensor adopting double precision conductive plastic potentiometers to realize complementary measurement

The utility model relates to a wind direction sensor adopting double precision conductive plastic potentiometers to realize complementary measurement. A shaft rod connecting sleeve is fixed on a rotary shaft of a coaxial duplex conductive plastic potentiometer, and one end of a shaft rod and the shaft rod connecting sleeve are fixed. An internal shell is sleeved in the coaxial duplex conductive plastic potentiometer. The other end of the shaft rod is fixed with a potentiometer adjusting wheel. A connecting sleeve and the internal shell are fixed. The lower end of the connecting sleeve and a circuit board are fixed. The coaxial duplex conductive plastic potentiometer is connected with the circuit board. One end of an aviation plug and the circuit board are fixed in a welding way. The aforementioned structure is arranged inside an upper shell. A lower shell and the upper shell are fixed. The other end of the aviation plug is locked on the upper end surface of the lower shell. The other end of the shaft rod pene
