TCRT5000 Line Tracking Sensor Module
The TCRT5000 Line Tracking Sensor Module is a compact and reliable infrared reflective sensor designed for detecting black and white surfaces. It is widely used in line follower robots, edge detection systems, and surface color detection projects. The module integrates an IR LED and phototransistor, making it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers.
This sensor works by emitting infrared light and measuring the reflected signal. White surfaces reflect more IR light, while black surfaces absorb it—allowing precise line detection for robotics and automation projects.
Key Features

Applications / Projects
Line follower robots (single or multi-sensor arrays)
Obstacle and edge detection
Black/white surface detection
Speed line counters
Robotics competitions & STEM projects
DIY automation and smart vehicles
How It Works
The IR LED emits infrared light onto the surface.
White surface → more reflection → sensor output changes
Black surface → less reflection → sensor output changes
The onboard comparator converts this into a clean digital signal for your controller.
Compatibility
Arduino Uno / Nano / Mega
ESP32 / ESP8266
Raspberry Pi (via GPIO with proper logic)
Other 3.3V / 5V microcontrollers
