The Cobra Line Follower Sensor V3 utilizes an infrared LED and phototransistor pair to perform reflectance sensing. The emitted IR light reflects off a surface, and the amount of reflected light received is measured, allowing the sensor to distinguish between high-reflectance (light) and low-reflectance (dark) areas. This differential measurement provides accurate line tracking for autonomous robot navigation.
Designed for stability in educational and competitive robotics environments, the sensor features a consistent 3.3V power requirement and outputs a simple digital or analog signal proportional to the reflected intensity. Its wide operating temperature ensures reliable function in various indoor and controlled outdoor settings, making it a core component for line-following, edge detection, and basic proximity sensing applications.
