Fc 51 Ir Sensor Datasheet =link= Jun 2026

The FC-51 module utilizes an infrared transmitter (IR LED) and an infrared receiver (Photodiode) mounted side-by-side.

pinMode(2, INPUT); pinMode(13, OUTPUT); if (digitalRead(2) == LOW) digitalWrite(13, HIGH); else digitalWrite(13, LOW);

Emits an infrared beam at a specific frequency.

The FC-51 IR sensor has the following features: Fc 51 Ir Sensor Datasheet

// FC-51 IR Sensor Connection Example const int SENSOR_PIN = 2; // OUT pin connected to digital pin 2 const int LED_PIN = 13; // Onboard Arduino LED void setup() pinMode(SENSOR_PIN, INPUT); // Set sensor pin as input pinMode(LED_PIN, OUTPUT); // Set LED pin as output Serial.begin(9600); // Initialize Serial Monitor void loop() int sensorState = digitalRead(SENSOR_PIN); // The FC-51 outputs LOW (0) when an obstacle is detected if (sensorState == LOW) digitalWrite(LED_PIN, HIGH); // Turn on LED Serial.println("Obstacle Detected!"); else digitalWrite(LED_PIN, LOW); // Turn off LED Serial.println("Path Clear"); delay(100); // Small delay to avoid flooding the serial monitor Use code with caution.
