Rotary Encoder 360 Degree Module        

The rotary Incremental encoder is used to measure the speed and with PWM technology can achieve rapid speed devices

With fixed bolt hole for easy installation
Great for DIY project

It is a Bread Board Friendly extremely precise module that provides an indication of how much the knob has been rotated and what direction it is rotating in. It is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code
