The IR Infrared 4 Channels Obstacle Avoidance Sensor Module Kit is a versatile solution designed for robots to navigate and avoid obstacles. Featuring four infrared sensors, it excels in intelligent tracking and black-and-white line recognition tasks. The module detects obstacles in the robot's path, facilitating direction changes to prevent collisions. Its four IR channels provide a broad field of view for accurate obstacle detection from multiple directions. Additionally, it offers black-and-white line recognition by detecting the contrast between a black line and a white surface, enabling precise path following. Ideal for autonomous vehicles and mobile robots, this module is easily integrated into a robot's control system, customizable for various applications and environments.
