By rotating the rotary encoder can be counted in the positive direction and the reverse direction during rotation of the output pulse frequency, unlike rotary potentiometer counter, which species rotation counts are not limited
With the buttons on the rotary encoder can be reset to its initial state, that starts counting from 0.
How it works: incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors.
These pulses are used to control angular displacement;Working Voltage: 5V
5 x KY-040 360 Degree Rotary Encoder Module
How it works:incremental encoder is a displacement of the rotary pulse signal is converted to a series of digital rotary sensors.
These pulses are used to control angular displacement.
In Eltra angular displacement encoder conversion using a photoelectric scanning principle.
Reading system of alternating light transmitting window and the window is not consisting of radial indexing plate (code wheel) rotating basis, while being an infrared light source vertical irradiation light to the code disk image onto the receiving on the surface.
Receiver is covered with a diffraction grating, which has the same code disk window width.
The receiver's job is to feel the rotation of the disc resulting changes, and change the light into corresponding electrical changes.
Then the low-level signals up to a higher level, and generates no interference square pulse, which must be processed by electronic circuits.
Reading systems typically employ a differential manner, about the same but the phase difference of the two waveforms different by 180 compared to the signal in order to improve the quality and stability of the output signal.
Reading is then the difference between the two signals formed on the basis,thus eliminating the interference.
"li"5pcs 360 Degree Rotary Encoder Module KY-040 Brick Sensor Development Board for Arduino
Specification of Rotary Encoder Module:
"li"Working Voltage: 5V
"li"Material: PCB + Brass
"li"Size: 32 x 19 x 30mm
"li"No Limited Rotation Counts:The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited.
"li"Encoder Key:With the key on the rotary encoder, you can reset to the initial state, that is, counting from 0.
"li"Application:For stepper and servo motor control. You could also use it to control devices like digital potentiometer.
The pin outs for this rotary encoder are identified in the below.
CLK: Encoder Pin A
DT: Encoder Pin B
SW: No Pushbutton Switch
+: 5V Supply
GND: Encoder Pin C
Pin connected to Arduino:
CLK = [pin 3]
DT = [pin 4]
Button = [pin 5]
+ = [Pin 5V]
GND = [pin GND]
Pin connected to Raspberry Pi:
CLK = GPIO16 [pin 36]
DT = GPIO15 [pin 10]
SW = GPIO14 [pin 8]
+ = 3.3V [pin 1]
GND = ground [pin 6]
