ITEM NAME:5PCS KY-040 Rotary Encoder Module Brick Sensor Development for Arduino TE17 W7W2 5PCS KY-040 Rotary Encoder Module Brick Sensor Development for Arduino TE17 W7W2 Material: Electronic components + PCB Operating voltage: 5V; Pulse circle: 20 Black colour; Size: About 31 * 19 * 29 mm By turning the rotary encoder can be counted in the positive direction and the opposite direction during the rotation of the output pulse frequency, unlike rotary potentiometer counting, this rotation counts are not limited. With the keys of the rotating encoder, the latter can be reset to its initial state, that is to say, it starts counting from 0 How does it work: Incremental encoder is a shift of the pulse signal is converted into a series of digital rotating sensors. These pulses are used to control the angular displacement. In Eltra conversion angular position transducer using a photoelectric scanning principle. Reading system of the alternating light transmission window and the window is not constituted by radial dividing disk (rotational code) rotation, despite being a light source of irradiation vertical infrared light for the code disk image on the receiver on the surface. Receiver is covered with a diffraction grating, which has the same width as the code disk window. The task of the receiver is to feel the rotation of the resulting disk changes and to modify the light in corresponding electrical variations. Then the low level signals up to a higher level, and does not generate square pulse interference, which must be processed by electronic circuits. Reading systems typically employ differential mode, about the same, but the phase difference of the two different waveforms of 180 with respect to the signal in order to improve the quality and stability of the output signal. The reading is therefore the difference between the two signals formed on the base, thus eliminating the interference. Packing: 5 x KY-040 Rotary Encoder Module Brick Sensor Development For Arduino O.With the keys of the rotating encoder, the latter can be reset to its initial state, that is to say, it starts counting from 0.
