Fc 51 Ir Sensor Datasheet
Based on your request, here is the technical information and specification summary for the .
The LM393 compares this voltage drop to the potentiometer setting. If the reflection is strong enough, the comparator flips the OUT pin to 0V. Interfacing FC-51 with Arduino
Triggers automatic water faucets, hand sanitizers, or paper towel dispensers when hands approach. Limitations and Troubleshooting Fc 51 Ir Sensor Datasheet
Suitable for obstacle detection at low to medium speeds (e.g., small robots, conveyor belts).
Because the sensor relies on light reflection, surface color and texture drastically impact performance: Based on your request, here is the technical
Use a small screwdriver to turn the onboard : Clockwise: Increases the detection distance threshold.
The onboard IR transmitter constantly emits invisible infrared light waves into the surrounding environment. // Since output is Active LOW
This article serves as your complete . We will cover everything from technical specifications and pin configuration to wiring diagrams, calibration, troubleshooting, and sample code.
// Since output is Active LOW, "LOW" means object detected if (sensorState == LOW) digitalWrite(ledPin, HIGH); Serial.println("Obstacle detected!"); else digitalWrite(ledPin, LOW); Serial.println("Path clear");
The module features a small, single-turn potentiometer (trimpot) located on the PCB.
