Outputs LOW (0) when an obstacle is detected and HIGH (1) when no obstacle is present. Compatible with both 3.3V and 5V microcontrollers.\u003c\/p\u003e\n\u003cp\u003eDetection Range: Adjustable sensing distance from 2–40 cm, with excellent interference resistance.\u003c\/p\u003e\n\u003cp\u003eNote: Detection distance varies depending on the object's color and surface reflectivity. Dark or black objects reflect less infrared light and are detected at shorter distances. The rated 2–40 cm range is measured using a white surface.\u003c\/p\u003e\n\u003cp\u003eWide Applications: Ideal for:\u003c\/p\u003e\n\u003cp\u003eSmart robot car obstacle avoidance\u003c\/p\u003e\n\u003cp\u003eBlack\/white line tracking\u003c\/p\u003e\n\u003cp\u003eEdge\/fall detection\u003c\/p\u003e\n\u003cp\u003eObject counting\u003c\/p\u003e\n\u003cp\u003eConveyor\/cutting line detection\u003c\/p\u003e\n\u003cp\u003eLiquid level detection\u003c\/p\u003e\n\u003cp\u003eWorks in Complex Environments: Optimized for black line tracking on white paper as well as colored or concrete surfaces.
