Feature: 1. Wind Direction Sensor: The all round 360 degree wind direction sensor comes with excellent linearity, high accuracy, no dead points, strong lightning resistance, easy observation, and reliable stability. 2. Wind Direction Indicator Shell: Small rotational resistance, accurate measurement, small size, light weight, easy to carry and assemble. It has a simple design, but very practical in use, giving you a good using experience. 3. ABS Material: Made with a low inertia ABS wind vane, the sensor exhibits good dynamic characteristics and responds well to wind direction changes. Safe to use. Boasting wonderful performance and strong stability. 4. Working Principle: The wind direction sensor operates primarily by rotation. This working principle enables accurate measurements of the wind's direction. It can be used outdoors for a long time. 5. Wide Application: Ideal for meteorology, environmental monitoring, aviation, and aerospace. It aids in understanding wind conditions and implementing corresponding measures.
