Description

The Photoelectric Beam Speed Sensor Module (Slot-Type Optocoupler) is a high-precision infrared detection module used for speed measurement, counting, and motion sensing in robotics and automation projects. It features a U-shaped slot-type IR emitter and receiver pair , which detects objects passing through the slot by interrupting the infrared beam. When an object passes through, the module generates a digital pulse output that can be counted to measure rotational speed (RPM) or linear movement . Compatible with Arduino, AVR, PIC, ESP32 , and other microcontrollers, this module is ideal for building tachometers, encoder wheels, and motor control systems .

Key Features

High-speed response and accurate counting performance.
Simple 3-pin interface for quick integration.
Adjustable threshold via onboard potentiometer (if equipped).
Compact, lightweight, and durable design.
Works perfectly for motor speed measurement, encoder disks, and line interruption detection .
