KY-040 Module:
360 degree rotary encoder module KY-040 FOR ARDUINO module
for Arduino rotary encoder module KY-040
Working voltage: 5V
Number of pulses in one circle: 20
The rotary encoder can count the number of output pulses during the rotation in the positive and negative directions by rotation. The rotation count is not like the potentiometer. There is no limit to this rotation count. With the button on the rotary encoder, it can be reset to the initial state, that is, counting from 0.
working principle:
An incremental encoder is a rotary sensor that converts rotational displacement into a series of digital pulse signals. These pulses are used to control the angular displacement. The angular displacement conversion in the Eltra encoder uses the principle of photoelectric scanning. The reading system is based on the rotation of the radial indexing plate #40; code wheel #41; which is composed of alternating light-transmissive windows and opaque windows, and is simultaneously illuminated by an infrared light source, and the light projects the image of the code wheel to On the receiver surface. The receiver is covered with a diffraction grating having the same window width as the code wheel. The job of the receiver is to experience the changes in the rotation of the disc and then to convert the changes in light into corresponding electrical changes. The low level signal is then raised to a higher level and a square pulse is generated without any interference, which must be handled by electronic circuitry. The reading system is usually differential, comparing two signals with the same phase but 180¡ã phase difference; to improve the quality and stability of the output signal. The reading is based on the difference between the two signals, eliminating interference.

The low level signal is then raised to a higher level and a square pulse is generated without any interference, which must be handled by electronic circuitry. The reading system is usually differential, comparing two signals with the same phase but 180¡ã phase difference; to improve the quality and stability of the output signal. The reading is based on the difference between the two signals, eliminating interference.\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eCap size:\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eDiameter: 15MM\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eHeight: 13.5MM\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eInner hole diameter: 6MM\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eColor: black (spot)\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003eInner hole: half shaft hole (D type hole)\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003ePackage Included:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cspan style=\"max-width: 100%; word-break: break-word; font-size: 16px;\"\u003e5 x KY-040 Module With Caps\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H481112bf63764b3a915fe5696d568c2d4.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hd64c90ec80c54f78bd9908523ab3ab979.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H1c4bcdebc7f84fed85bc296b763679805.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H7936ebb9b94e41fcb420628f3863ba6f9.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Hc1ab6726a06f4e34b158d69c0142431bl.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H8712a0a231e744c5a89aa3243bf813d38.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin: 0px; line-height: inherit; color: #000000; font-family: 'Open Sans', Arial, Helvetica, sans-serif, Heiti;\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/H70d67c356bce4a12a525fb3ea8931432k.jpg\" style=\"border-style: none; vertical-align: middle; width: 1000px;\"\u003e\u003c\/p\u003e"}
