The FC-51 module features a simple, standardized 3-pin interface, making it easy to connect directly to microcontrollers like Arduino, Raspberry Pi, or ESP32.

To reliably detect objects at different distances, use the onboard potentiometer. Follow these steps: Troubleshooting Guide Potential Cause Always outputs LOW /

Used to adjust the detection range sensitivity. Turning it clockwise increases the detection distance.

Absorb IR light. A pure matte black surface may not reflect enough light to trigger the sensor at all, a property frequently exploited in line-following robots where black tape represents a boundary line. Adjusting Sensitivity and Range

The FC-51 is an , designed primarily for obstacle detection and proximity sensing . It is highly popular in the maker and robotics community due to its low cost, ease of use, and simple digital interface. The module is frequently used in DIY electronics, microcontroller projects, and educational settings.
