Trace Module TCRT5000 Sensor Probe Intelligent Car Infrared Tracking

The TCRT5000 Infrared Tracking Module is a reflective IR sensor used for line-following robots, intelligent car navigation, obstacle detection, and automated control systems. It offers high sensitivity, fast response, analog/digital output options, and stable performance under varying light conditions.

Trace Module TCRT5000 Infrared Tracking Sensor

The Trace Module TCRT5000 Infrared Tracking Sensor is one of the most essential and widely used modules in robotics, automation, and smart car systems. Powered by the highly reliable TCRT5000 reflective optical IR sensor, this module enables intelligent robots to detect black/white lines, edges, and reflective surfaces with exceptional accuracy. Whether you are building a line-following robot, creating an automated sorting system, or integrating sensing features into an Arduino or NodeMCU IoT-based project, this module provides a simple yet powerful solution.

Designed for stability and improved environmental resistance, the TCRT5000 IR module uses an infrared LED emitter and a phototransistor receiver to analyze reflected IR light. Dark surfaces absorb IR light while lighter surfaces reflect it, allowing the module to easily identify transitions. This makes it perfect for robotic navigation, maze-solving applications, and industry-grade automation tasks where precision and responsiveness are critical.
