CALT 360 Degree 22mm Outer 6mm Shaft Hall Effect Potentiometer Angle Encoder Sensor Analog 0-5v Output 5V Supply Voltage

I bought this product to make a Proportional Integral Derivative (PID) Motor placement to have 360 degree placement. It does what it says that it is 360 degrees but it is not accurate when taking high speed input. you can rotate this 180 to the right and 180 back to the left and it will show the same analog signal. It has a chip in it that interprets a magnets polarity and calculates it to an analog signal. Not very speedy or accurate.
