KY-040 rotary encoder module
Working voltage: 5V
Number of pulses per cycle: 30
The rotary encoder can count the number of pulses output during the forward and reverse rotation processes through rotation. Unlike a potentiometer, the rotation count has no limit. Combined with the buttons on the rotary encoder, it can be reset to the initial state, which starts counting from 0.
Working principle: 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. The conversion of angular displacement in the Eltra encoder adopts the principle of photoelectric scanning. The reading system is based on the rotation of a radial indexing disk (code disk) composed of alternating transparent and opaque windows, while being vertically illuminated by an infrared light source, which projects the image of the code disk onto the surface of the receiver. The receiver is covered with a layer of diffraction grating, which has the same window width as the code disk. The job of the receiver is to sense the changes caused by the rotation of the optical disc, and then convert the light changes into corresponding electrical changes. To raise the low-level signal to a higher level and generate square pulses without any interference, electronic circuits must be used for processing. The reading system usually adopts a differential method, which compares two different signals with the same waveform but a phase difference of 180 °, in order to improve the quality and stability of the output signal. The reading is formed based on the difference between the two signals, thereby eliminating
