The KY-040 Rotary Encoder Module, is an incremental electro-mechanical device 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

By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which Species rotation counts are not limited. With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0. The output of incremental rotor encoders provides information about motion of shaft, which is typically further processed in processor/controllers into information such as speed, distance and position.
