Could this be used as the basis for a weathervane (continuous 360 degree movement without hard stops)?

Is this angle sensor Bi-Directional? Does every angle 0-360 degrees have a unique voltage output regardless of rotation direction? In other words can I go back and forth between two angles (changing directions) and the value changes back to what it was at the original angle?
Example: at 0 Degrees let's say 0.1V output. I go clockwise 90 degrees and it's 1.1V. If I go back the other way (CCW) and return to 0 Degrees is it going to be 0.1V or not? Or can it only be accurate if you only rotate in the clockwise rotational direction?
JaneYu Why is the output value different depending on the direction? https://uploads.disquscdn.c...
JaneYu Does this sensor always transmit the current angle value?.
i.e. does every angle value correspond to a single analog output value between 0 - 5 V?
JaneYu Yes,but pay attention to:
This angle sensor is 12-bit resolution, and UNO is a 10-bit AD, so it will lose some accuracy.
Thank you for the immediate response!!! Would it be possible to suggest something that is absolute, has a relatively good accuracy (up to 2-3 degrees) and has a long life span? 50.000 cycles, which is what I have seen in some absolute rotary encoders is not enough, a couple of million would be great
JaneYu Hi, I would like to ask if this sensor is absolute, in the sense that it "stores" the current angle, like absolute rotary encoders do.
Thank you.
JaneYu Can I use this for building a steering wheel with arduino?
JaneYu Hey,
The sensor will allow you to get specific angle readings. Although I do not know the exact specifications of how you plan to build a steering wheel, if this data is relevant to your project then yes!
