10 mm Arduino RPM Sensor

The 10 mm Arduino RPM Sensor is a compact, reliable rotational speed measuring module built for motor control, robotics, and industrial automation. Using an infrared (IR) reflective sensor, it detects the rotation of a marked surface or encoder disc to calculate real-time revolutions per minute (RPM) with excellent accuracy. This makes it perfect for DIY electronics, IoT devices, and embedded systems that need precise speed feedback.
