Features  

• Built-in high-precision 5mm optical slot facilitates instant counting when paired with an encoder disk.  
• Utilizes a reliable LM393 comparator chip ensuring clean, stable digital square-wave pulse waveforms.  
• Equipped with dual onboard LED status indicators tracking real-time power supply and signal changes.  
• Features an integrated M3 mounting hole allowing quick, vibration-resistant placement on robot chassis.  
• The MH Infrared Speed Sensor Module LM393 Slotted Optocoupler 1Pack is a highly accurate, industry-standard optical counting tool designed for smart car chassis tracking, motor speed measurement, and pulse counting automation.
• Operating smoothly within a 3.3V to 5V DC power envelope, this module centers around a 5mm wide slotted infrared optocoupler housing.
• When an opaque object or encoder wheel tooth blocks the optical path inside the groove, the digital output pin (DO) instantly generates a crisp TTL logic high signal, which can be direct-coupled to microcontrollers like Arduino or Raspberry Pi.
• The board architecture features a precise LM393 comparator to eliminate mechanical signal bounce and noise interference, outputting flawless square waves.
• Compact yet robust with a pre-drilled M3 mounting slot, it is the perfect fit for industrial tachometers, automated production line counters, and DIY educational robotics.
