This rotation sensor from Waveshare detects clockwise/anti-clockwise rotations: degrees and laps.
An incremental encoder is a kind of rotation sensor for translating the rotary displacement into a sequence of digital pulse signals. The displacement can be gained by counting the number of pulses 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.

In the case of working with an MCU:
- VCC ↔ 3.0V ~ 5.3V
- GND ↔ power supply ground
- SW ↔ MCU.IO (encoder button status)
- SIB ↔ MCU.IO (output status)
- SIA ↔ MCU.IO (output status)
