Infrared reflective Photoelectric Switch IR Barrier Line Tracking sensor TCRT5000L Arduino

The TCRT5000L Photoelectric Reflection Module utilizes a TCRT5000 to detect color and distance. It emits IR and then detects if it receives the echo.


TCRT5000L Photoelectric Reflection Module sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black.

The measuring distance ranges from 1mm to 8mm, and the central point is about 2.5mm. There is also an on-board potentiometer to adjust the sensitivity.

Basically, the infrared diode will emit the infrared continuously when the module connects to the power. Accordingly, when the emitted infrared light is not reflected or the strength is not big enough, the triode will be off, at this time, D0 output logic LOW and the signal indicator LED off.

TCRT5000L Photoelectric Reflection Module Features

  • Supply Voltage: 3.3V~5V
  • Detect distance: 1mm-8mm
  • Digital Outputs HIGH when the sensor detects objects or white lines
  • On-board indicator LED to show the results
  • On-board potentiometer to adjust the sensitivity
  • Utilizing LM393 chip

TCRT5000L Photoelectric Reflection Module Applications

  • Position sensor for shaft encoder
