AJMRTC groove coupler beam photoelectric sensor module is built around the LM393 comparator. It uses slot optocoupler principle to detect blockage inside the gap, which can realize motor speed measurement and pulse counting. The onboard potentiometer allows users to adjust trigger sensitivity, and the LED indicator shows working state conveniently. Powered by DC3.3V-5V, this module can directly connect with Arduino and other microcontrollers. It fits for motor rotation counting, speed monitoring, object counting and various electronic prototype experiments.
