is a high-performance sensor module designed specifically for line-following robots and automation systems. It uses an array of three infrared (IR) sensors to accurately detect black or white lines on various surfaces, making it an essential component for robotics enthusiasts, students, and developers working on intelligent navigation systems.

Key Features

• Accurate Line Detection –  uses three high-quality IR sensors that work together to identify lines with precision. It can detect changes in reflectivity between black and white surfaces, enabling smooth and stable motion for robotic platforms.

• Adjustable Sensitivity – Each channel includes a potentiometer, allowing users to fine-tune the sensitivity according to different lighting conditions or surface materials. This ensures reliable performance both indoors and outdoors.

• Wide Operating Voltage – The module operates within a voltage range of 3.3V to 5V, making it compatible with popular microcontrollers such as Arduino, Raspberry Pi, and ESP32 boards.

• Fast Response Time – Designed with efficient circuitry, it provides real-time detection suitable for high-speed robotic applications.

• Easy Integration – The module features a simple pinout (VCC, GND, OUT1, OUT2, OUT3) and can be easily connected via jumper wires. Its compact design fits perfectly on small robotic chassis.
