Drehgebermodul für Arduino Brick Sensor Development, runde Audio-rotierende Potentiometer-Knopfkappe EC11
Incremental encoder is a rotary sensor that converts rotational displacement into a series of digital pulse signals. These pulses are used to control angular displacement. In Eltra Encoding: The conversion of angular displacement in the device adopts the principle of photoelectric scanning. The reading system consists of a radial indexing disk composed of alternating transparent and opaque windows Based on the rotation of the code wheel, it is simultaneously illuminated vertically by an infrared light source, which projects the image of the code wheel onto the surface of the receiver. The receiver is covered with a diffraction grating, which has the same window width as the encoder. The job of the receiver is to sense the changes caused by the rotation of the optical disc Then convert the light changes into corresponding electrical changes. Make the low-level signal again Rising to a higher level and generating square pulses without any interference, This must be handled using electronic circuits. Reading systems typically use differential methods, Two waveforms are about to be generated, but with a phase difference of 1 Compare different signals at 80 ° to improve the quality of the output signal Quantity and stability. Reading is the basis for the difference between two signals Formed on top, thus eliminating interference.
