Rotary Encoder Module KY-040

A rotary encoder is an incremental electromechanical component with a shaft that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor / controllers into information such as speed, distance, and position. The shaft has unlimited 360 degree rotation.
