TCRT5000 and TCRT5000L are reflective sensors which includes an Infrared emitter and a Photodetector in a single package. The package includes two mounting clips and four solderable leads. TCRT5000L is a long lead version and the leads can also be trimmed to convert it to TCRT5000. Emitter and Detector are arranged in the same direction to sense the presence of an object by using reflective IR beam from an object
The module has four pins - Two for Emitter LED and two for Receiver (Photodetector) LED.
  • Photodetector and Emitter circuit in a single package
  • Breadboard Compatible
  • Compact construction
  • Sense presence of an object by using reflective IR beam from an object
  • Plastic polycarbonate housing construction to prevent crosstalk
  • Position sensor for shaft encoder
  • Detection of reflective materials such as paper, magnetic tapes, encoders, etc
  • Limit switch for mechanical motion applications
  • Line follower Robots
  • General purpose - wherever the space is limited
Application Circuit
TCRT5000 Application Diagram
Infrared Reflector consists of 2 parts : The emitter and detector. The application circuit shows the functionality of the module. The transmitter shoots out Infrared light which bounces off any surface. The detector captures this light and indicated on the output pin.

This module can act as an analog sensor, or a digital sensor depending on the application requirement. Output voltage from the module is between 0v to 5V and proportional to received beam of light. You can either use a microcontroller to detect analog range or use an Operational amplifier to convert analog voltage into digital voltage.
