KY-033 Infrared Line Tracking Sensor Module (Black & White Line Detection Module)

The KY-033 Infrared Line Tracking Sensor Module is a compact reflective infrared sensor designed to detect black and white surface contrast for line-following and navigation applications. It emits infrared light toward a surface and measures the reflected signal to determine whether a dark or light surface is present. The module provides a digital output for direct interfacing with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms, making it ideal for robotics, autonomous vehicles, and automation projects.
