Fc 51 Ir Sensor Datasheet Guide

If your FC-51 module is not performing as expected, review the following debugging steps: Scenario A: The Obstacle LED is always ON

Receives the reflected IR light from an object.

If no obstacle is present, the light radiates outward and dissipates. When an object passes in front of the sensor, the IR light bounces off the object's surface. Fc 51 Ir Sensor Datasheet

The FC-51 module integrates several key components on a single printed circuit board (PCB):

The following code configures Pin 2 as an input, monitors the sensor status, and prints the result to the Serial Monitor. If your FC-51 module is not performing as

Clockwise rotation increases detection distance; counter-clockwise decreases it. How the FC-51 Sensor Works

Sunlight and incandescent bulbs emit massive amounts of infrared light, which can blind or saturate the IR receiver. The FC-51 module integrates several key components on
