ITEM NAME:Encoder module Brick Sensor Development KY-040 for Arduino Compatible I3D3 Encoder module Brick Sensor Development KY-040 for Arduino Compatible I3D3 By rotating the rotary encoder can be counted during the rotation of the output pulse frequency in the positive direction and the reverse direction, unlike potentiometers numerator, the Species speeds are not limited. Using the buttons on the encoder can be set back to the initial state, the Counting starts from 0. How it works: Incremental is a displacement of the rotational pulse signal is converted into a series of digital encoders. These pulses are used to control angular displacement. Color: As shown Material: ABS metal Package list: 1 x Encoder Reading system of alternating light transmissive window and the window is not of radial indexing plate (code wheel) rotating basis, while an infrared light source vertical irradiation light to the code disk image to the reception on the surface. Receiver is with a diffraction grating having the same code disk window width has covered. Job recipient is from feeling the rotation of the disc resulting Vera end stanchions, and amend the light into corresponding electrical changes. Then the low-level signals will be up to a higher level, and does not generate interference rectangular pulse, which must be processed by electronic circuits. Reading systems typically utilize a differential manner approximately the same, but the phase difference of the two waveforms 180 degrees different in comparison to the signal in order to improve the quality and stability of the output signal. Reading educated the difference between the two signals on the base, whereby the interference Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/-1-3cm..Using the buttons on the encoder can be set back to the initial state, the Counting starts from 0.
