Product Overview

This product features a compact, lightweight, and aesthetically robust design, making it easy to carry and assemble. The wind vane shape is reasonably designed to accurately locate atmospheric wind direction in nature. Made of polycarbonate material, it offers advantages such as rain resistance, corrosion resistance, aging resistance, and durability.

Features

◆ Small size, lightweight, extremely convenient for field carrying and installation; waterproof and shockproof structural design suitable for outdoor use

◆ High detection accuracy; system adopts low-power, energy-saving design with digital processing technology

◆ Wide range and excellent stability

◆ Good linearity in data information display; long signal transmission distance; strong resistance to external interference

Working Principle

Internally equipped with a Hall angle sensor and a low-inertia lightweight metal wind vane to respond to wind direction. When the wind direction changes, the tail vane rotates, driving the shaft magnet to turn via the rod, thereby outputting a varying voltage signal.
