Wind speed and wind direction integrated detection sensor

The invention provides a wind speed and wind direction integrated detection sensor, which comprises a shell, a wind cup/wind direction fan blade connected with the shell, and a non-contact magnetic rotary encoder arranged in the shell, the non-contact magnetic rotary encoder comprises a shaft rod and a two-pole magnet at the lower end of the shaft rod, and a magnetic induction chip is arranged below the two-pole magnet; the wind cup/wind direction fan blade drives the shaft rod and the magnet to rotate synchronously, the magnetic induction chip senses magnetic field changes, the relative angleposition of the magnet is measured, and the wind speed/wind direction value is obtained through calculation. The wind speed sensor and the wind direction sensor adopt thenon-contact magnetic rotary encoder in a unified manner in the aspect of acquisition principle, the two-pole magnet rotates in the center of the chip, the magnetic rotary encoder can measure the relative angle positions of the magnet, the precision can r
