Photoreflector V2 is an intelligent sensor modules that can be used to detect objects / bands of color (light colored lines with a dark background or vice versa). This module is able to learn to distinguish the lines and backgrounds, and able to adapt to changes in ambient light. The sensor module is equipped with a TTL UART and I2C interface. Examples of applications Photoreflector V2 among others to line tracking / following, robot navigation, obstacle detection, or other applications that use pronsip light reflection.
