Speed Measuring Groove Sensor Module – Infrared Coupler for Arduino

The Speed Measuring Groove Sensor Module is a compact and efficient infrared sensor designed for precise rotational speed detection in robotics and automation systems. Featuring a U-shaped opto-interrupter (groove coupler), this sensor detects objects passing through the slot and produces a clean digital output signal, making it perfect for motor speed encoders, object counters, and real-time feedback systems.

Compatible with Arduino, Raspberry Pi, and other microcontrollers, the sensor provides a simple yet accurate way to measure speed or count revolutions in motors and wheels. It is widely used in line-following robots, speed-regulated motors, conveyor systems, and DIY embedded electronics where speed monitoring is critical.
