Fc 51 Ir Sensor Datasheet !!better!! ✦ Easy & Recent

The FC-51 module is compact and features a small number of components. Understanding the layout is crucial for correct wiring.

When working with the FC-51 IR sensor, keep the following tips and precautions in mind:

The onboard IR LED continuously emits invisible infrared light at a specific frequency. Fc 51 Ir Sensor Datasheet

What you are using (Arduino, ESP32, Raspberry Pi)? What is your target obstacle material ?

The module features a small, single-turn potentiometer (trimpot) located on the PCB. The FC-51 module is compact and features a

if (sensorValue == LOW) // Check if an obstacle is detected digitalWrite(ledPin, HIGH); // Turn on the LED Serial.println("OBSTACLE!!"); else digitalWrite(ledPin, LOW); // Turn off the LED Serial.println("CLEAR");

When an object enters the detection range, the emitted IR light bounces off the surface of the object. What you are using (Arduino, ESP32, Raspberry Pi)

It uses an LM393 comparator for stable, fast performance, which is often quicker than ultrasonic sensors for simple binary obstacle detection.
