We will learn how to use this analog wind direction sensor This is a Chinese wind direction sensor, sometimes it is just really hard to get the datasheet, or we can’t read the datasheet in Chinese. Let’s see the specification first, I don’t read Chinese but I think the label means operating voltage or voltage input is 12-24 volt. And the output is 0-5 volt.

Three-axis means this sensor can detect movement on X, Y, Z-axis or usually we called that 3 axis magnetometer. So it’s not only the direction in the degree that we are able to extract.
