Fc 51 Ir Sensor Datasheet
Wiring the FC-51 to an Arduino is straightforward:
Search the module name "FC-51 IR sensor datasheet" plus the vendor name or part number printed on the PCB; look for PDF datasheets from electronics suppliers or manufacturers.
This article serves as your complete . We will cover everything from technical specifications and pin configuration to wiring diagrams, calibration, troubleshooting, and sample code. Fc 51 Ir Sensor Datasheet
The signal pin. It outputs a logical LOW (0V) when an obstacle is detected within the set threshold. It outputs a logical HIGH (VCC) when the path is clear. Hardware Components and Adjustment
: The transmitter continuously sends out IR waves at a specific frequency. Wiring the FC-51 to an Arduino is straightforward:
This code prints "OBSTACLE!!" to the serial monitor when an object is detected.
Look at the silkscreen on the PCB. Most modules are labeled "FC-51" and have pins marked as + , OUT , - or similar. Use a continuity tester to confirm ground connections. The signal pin
void loop() int irSensorValue = digitalRead(irSensorPin); if (irSensorValue == HIGH) Serial.println("Obstacle detected!"); else Serial.println("No obstacle detected.");
Line following (can distinguish between black and white surfaces). Hand-wave switches or touchless triggers.
To use the FC-51 effectively, you it using the on-board potentiometer. The calibration process adjusts the sensitivity threshold of the LM393 comparator.
