    LM393 Infrared Optocoupler Speed Sensor Module

    RBD-3805

    The LM393 Infrared Optocoupler Speed Sensor Module is designed for accurate motor speed measurement, pulse counting, and position detection in microcontroller-based projects. Using an infrared optocoupler sensor, it detects interruptions in the optical path (such as from a slotted wheel), generating a clean pulse output that can be read by Arduino, Raspberry Pi, or other microcontrollers.

    Description

    The LM393 Infrared Optocoupler Speed Sensor Module is designed for accurate motor speed measurement, pulse counting, and position detection in microcontroller-based projects. Using an infrared optocoupler sensor, it detects interruptions in the optical path (such as from a slotted wheel), generating a clean pulse output that can be read by Arduino, Raspberry Pi, or other microcontrollers.

    With its infrared LED and matched phototransistor design, the module minimizes interference from external light sources, ensuring stable and reliable performance even in challenging environments. The onboard LM393 comparator chip processes the signal, providing a clear digital output for further use in motor control and automation systems.

    Features

    • Operating Voltage: DC 5V

    • Output Signal: Digital pulse output

    • Chip: LM393 comparator

    • Dimensions: 32mm x 11mm x 20mm

    • Output Indicator LED for signal status

    • High output when path is blocked, low output when unblocked

    • Immune to interference from ambient light

    • Simple plug-and-play design for microcontrollers

    Applications

    • Motor speed measurement

    • Workpiece counting systems

    • Position limit sensing

    • Pulse counting experiments

    • Robotics and automation projects

     A compact, reliable, and cost-effective solution for real-time speed and counting applications in DIY electronics, robotics, and embedded system projects.
