Troubleshooting and Calibration
Keep in mind that the datasheet may vary depending on the manufacturer or the specific version of the sensor.
The sensitivity is set too high, or the sensor is detecting its own reflection from ambient surfaces.
Interfacing the FC-51 with an Arduino UNO is incredibly straightforward because it outputs a simple digital high/low signal, removing the need for analog-to-digital conversion formulas. Wiring Diagram Arduino UNO Pin Digital Pin 2 Arduino Example Code Fc 51 Ir Sensor Datasheet
The LM393 voltage comparator compares the receiver's signal against a threshold set by the onboard potentiometer.
Digital (High/Low). It typically outputs Low (0V) when an object is detected and High (VCC) when the path is clear. Detection Angle: Approximately 35°. Physical Components (The "Pieces")
