This is Waveshare Rotation Sensor.

Knob in the form of an encoder with a button that allows you to create a simple user interface. The module sends a digital signal on the SIA and SIB pins, depending on the direction of rotation. It works with voltages from 3 V to 5.3 V.

The sensor has a 5 pin connector with digital outputs SIA, SIB and SW to be attached to the pin of the microcontroller, e.g. Arduino.

Operating principle:
Incremental encoder is a kind of rotation sensor for translating the rotary displacement into a sequential of digital pulse signal. The displacement can be gained by counting the number of the pluses outputted in the course of clockwise or anticlockwise rotation. Comparing with the potentiometer, the rotary counter has no limit for counting. So, there is a reset button provided to
reset the counter to the initial state, restarting at 0


  1. It detects the clockwise and counterclockwise rotation
