Speed Measuring Sensor Counter Motor Test Groove Coupler Module (Optical Slot Speed Sensor Module)

The Speed Measuring Sensor Counter Motor Test Groove Coupler Module is an optical speed detection module designed for measuring the rotational speed of DC motors, geared motors, and rotating shafts. It uses an infrared slot-type optocoupler to detect encoder discs or slotted objects passing through the sensing gap and generates digital pulse signals proportional to the rotation speed. The module is compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other microcontroller platforms, making it ideal for RPM measurement, robotics, automation, motor testing, and embedded control applications.
