It is used to measure the rotation of a motor or shaft, providing feedback on speed, direction, and position. This makes it essential for applications like motor control, robotics, and precision movement systems. Answer: An encoder sensor module is a device that converts mechanical motion into electrical signals, allowing a microcontroller like Arduino to track the movement of a motor or shaft. <dl> <dt style="font-weight:bold;"> <strong> Encoder </strong> </dt> <dd> An encoder is a sensor that detects the position, velocity, or direction of a rotating shaft.
