5mm Groove Opto-Coupler Sensor Unit - 4 Channel
By using voltage comparator LM393, this mini Motor Speed Sensor moudle is used for motor motion control. It is designed on the basis of optical sensor by having the electrical circuit installed inside the plastic enclosure. It is easy to use due to its flexible positioning and easy installation. It is a very helpful item for making robotic chassis.
