Rotary Encoder LPD3806

Rotary Encoder LPD3806

  This module is ideally suited to adding rotation detection to your project and is compatible with microcontrollers such as the Arduino. The encoder lets you add control to your project similar to radio volume control knobs in cars and detecting rotation direction, speed in machines. The rotary 6mm shaft provides a large range of compatible knobs to choose from allowing you to get the right knob for your job.

     For measuring the rotational speed of the object, angle, acceleration, and length measurements.
     Suitable for intelligent control of various displacement measurement, automatic fixed-length leather automatic guillotine machine, steel fixed length cutting controller, civil measured height human scale, college game with robots.
