Note: The actual detection range varies based on the object's color and material. Reflective, light-colored surfaces are detected at greater distances than dull, dark surfaces. Pin Configuration (Pinout) Note: This is a synthesized feature datasheet
Suitable for obstacle detection at low to medium speeds (e.g., small robots, conveyor belts). Share public link Note: The actual detection range
