360 Degree Rotary Encoder Module KY-040 Compatible Brick Sensor Board for Arduino Raspberry Pi, Pack of 2
360 Degree Rotary Encoder Module KY-040 Compatible Brick Sensor Board for Arduino Raspberry Pi, Pack of 2
Description
Features:
- 360 Degrees rotary encoder module, model: KY-040, working voltage: 5V, pulse count per circle: 20.
- The rotary encoder can count the number of pulses output during the forward and reverse rotation by rotating. Unlike a potentiometer, the rotation count is not limited.
- The reading system usually adopts a differential method, that is, two different signals with the same waveform but a phase difference of 180 are compared in order to improve the quality and stability of the output signal.
- Incremental encoders give two-phase square waves, their phase difference is 90, usually called A channel and B channel.
- One of the channels gives information related to the speed. at the same time, the two channel signals are compared in order to obtain the information of the rotation direction.
