⚙️ LM393 Motor Speed Sensor Module – Groove Coupler Optical Encoder ⚙️
The LM393 Speed Sensor Module uses an infrared slot coupler to detect rotational speed or motion by counting interruptions in a light beam.
As an object (such as a wheel slot or encoder disc) passes through the sensor’s gap, it outputs digital pulses that can be easily read by Arduino, ESP32, or Raspberry Pi.
Perfect for robotics, automation, motor control, and speed measurement applications.
