The HW-040 rotary encoder module is a device that creates an electrical signal dependent on the amount and direction of rotation of the rotary input device (knob). It is a position sensor with a knob that may be used to precisely regulate stepper or servo motors.
The HW-040 rotary encoder module is a rotary encoder intended for use in electrical circuits and systems. A rotary encoder is a sensor that detects the position of a spinning shaft. The HW-040 module normally has three pins: VCC, GND, and Signal.
It creates a pulse train output with the number of pulses determined by the number of encoder detents. The amount of pulses per revolution varies according to the encoder, although it is typically between 20 and 24 pulses each revolution. This enables accurate position detection and rotational control of the shaft.
