RS485 Wind Vane Direction Sensor

The wind direction sensor, or wind vane, is a precise instrument utilized for measuring horizontal wind direction. It boasts a hall sensor embedded within its structure. Constructed from a durable aluminum alloy, the sensor undergoes a special precision die-casting process, resulting in minimal dimensional tolerance and impressive surface accuracy. Its internal circuit is fortified to deliver superior strength, weather resistance, anti-corrosion properties, and waterproofing.

The device features a corrosion-resistant military-grade plug for its cable connector, ensuring an extended service life. At the heart of its functionality is a low-inertia wind direction sensor. This component is adept at detecting changes in wind direction with agility. As the wind shifts, the tail wing pivots, driving the axle magnet through the shaft to yield precise wind direction data.

Capable of identifying up to 16 natural wind directions, this sensor demonstrates exceptional cost performance and is applicable across diverse fields, including meteorology, marine environments, environmental monitoring, airports, ports, laboratories, industrial contexts, agriculture, and transportation sectors.

The sensor operates through the interaction between the wind and the vane. The nose of the vane aligns with the wind direction as the wind influences its flat surface, causing it to rotate appropriately. This movement is translated into an electrical signal by a potentiometer or magnetic sensor attached to the vane, and further processed to ascertain the wind direction.
