The 4 Channel Infrared Tracking Sensor Module is a high-performance module designed for Arduino smart car line follower robots. It uses infrared reflection technology to detect black and white lines on surfaces, allowing your robot or automated vehicle to track paths, avoid obstacles, and prevent falls. Ideal for DIY robotics, smart car projects, and industrial automation systems, this sensor module provides stable and accurate signal output under various lighting and surface conditions.

Features:

• 4-Way Infrared Tracking: Equipped with four high-sensitivity infrared sensors for detecting black and white lines, enabling precise path following and line-tracking control.
• Line Following & Path Detection: Perfect for smart cars and robots that follow pre-defined black lines, making it ideal for line follower projects and patrol robots.
• Obstacle & Cliff Avoidance: Detects sudden drops or edges to prevent the robot from falling off a surface; also capable of detecting nearby obstacles using reflected infrared light.
• Adjustable Detection Range: Supports fine-tuning of detection distance from 1mm to 60cm, ensuring reliable performance based on surface reflectivity and environmental lighting.
• Stable and Fast Response: Infrared sensors provide quick and accurate signal output, allowing real-time control of motor direction and speed adjustments.
• Easy Integration with Arduino: TTL-level output makes it compatible with Arduino, Raspberry Pi, ESP32, and most other microcontroller platforms.
• Indicator LEDs for Each Channel: Built-in red LED indicators display sensor status for easy debugging and setup.
• Durable Construction: Features a hollow board + small forward plate design with standard M3 mounting holes, ensuring easy installation on robotic chassis.
• Versatile Applications: Suitable for robot line tracking, edge detection, obstacle detection, and automated industrial control.
