TCRT5000 Line Tracking Sensor Module – IR Reflective Optical Sensor for Line Follower Robots in Pakistan

Overview

The TCRT5000 Line Following Sensor is an infrared reflective module that packs an IR transmitter and an IR receiver into one compact unit. It works on the principle of light reflection: when the IR light hits a white surface, it reflects back to the receiver; when it hits a black line, the light is absorbed. This module features an LM393 voltage comparator chip, providing a clean digital signal that your Arduino or ESP32 can read instantly.

Key Features 

• Dual Output Mode: Includes both Digital (DO) for simple high/low detection and Analog (AO) for precise distance/reflection intensity measurements.

• Adjustable Sensitivity: Features an on-board potentiometer to fine-tune the detection threshold based on your track’s lighting conditions.

• Ambient Light Resistance: Designed to filter out standard room lighting, preventing “glitches” during your robot runs.

• Status Indicators: Built-in LEDs show power status and signal detection for easy troubleshooting.

• Easy Mounting: Includes a pre-drilled bolt hole for secure attachment to your robot chassis.
