Add rotational sensing - without a mechanical connection - with the Adafruit AS5600 Magnetic Angle Sensor. Featuring the classic ams AS5600, this board can sense a rotating N/S magnetic field up to 3mm away from the chip body. These sensors are often used to create 'frictionless' rotary encoders or potentiometers, without the risk of mechanical failure or noise. Magnetic angle sensors get the best of 'both worlds': like rotary encoders they can rotate freely 360 degrees around, and like potentiometers, they have absolute location detection.
