KY-033 TCRT5000 Infrared Tracking Sensor Module

The KY-033 Tracking Sensor TCRT5000 Reflective Photoelectric Switch Module is a highly sensitive, single-channel infrared obstacle and line detection sensor. It features the TCRT5000 infrared transmitter and phototransistor pair, which detects the presence of a reflective surface by emitting IR light and measuring the reflection. This module is widely used in DIY robotics to help smart cars track black lines on a white background or vice versa, providing a simple yet highly effective navigation solution.

Equipped with an onboard LM393 voltage comparator chip, the module delivers a clean, stable digital output signal with excellent driving capability. It includes a high-precision potentiometer to adjust the detection sensitivity, allowing you to calibrate the sensor for different surface textures and ambient lighting conditions. Compatible with popular microcontrollers like Arduino, Raspberry Pi, ESP32, and PIC, this compact sensor is perfect for students, makers, and professional developers building automated systems.

Features:

• TCRT5000 Optical Sensor: High-sensitivity infrared reflective sensor for reliable line and obstacle detection.
• Onboard LM393 Comparator: Ensures clean digital output signals with low noise and high stability.
• Adjustable Sensitivity: Features a multi-turn potentiometer to easily calibrate the detection threshold.
• Dual LED Indicators: Onboard power LED and status indicator LED for real-time visual feedback.
• Wide Compatibility: Operates seamlessly with 3.3V and 5V logic microcontrollers like Arduino and ESP32.
• Compact & Easy to Mount: Lightweight design with integrated mounting holes for secure installation on robot chassis.
