Hi,
the 4-quadrant sensor is an AS5050 from Austriamicrosystems. The resolution ist 10 bit.
If this is not good enough you can replace it by a AS5045 with 12 bit.
I am using an axis made of brass running in a sapphire. It is very sensitive. I was wondering
the windvane was continue moving without wind, it then behaves like a compass and shows
north!
The DIY Peet Bros sensor counts the revolution time to determine the wind speed and direction.
The metal sheet is used to seperate the sensors only. The resolution decreases with rising
windspeed.
The overall resolution limit is the ESP Microcontroller. I think it can be improved by counting
every second or third revolution depending on the wind speed.
