Fc 51 Ir Sensor Datasheet Here

The module uses a standard 3-pin male header for easy connection Art of Circuits ir sensor.docx - Slideshare

The following sketch reads the digital state of the FC-51 sensor and prints the status to the Serial Monitor. It also illuminates the built-in Arduino LED (Pin 13) when an obstacle is detected.

The FC-51 can run on 3.3V, making it safe for Pi GPIO. Use the same pinout but connect VCC to 3.3V.

// IR Obstacle Collision Detection Module int LED = 13; // Use the onboard Uno LED int isObstaclePin = 7; // This is our input pin int isObstacle = HIGH; // HIGH means NO OBSTACLE Fc 51 Ir Sensor Datasheet

Due to its fast response time and low power footprint, the FC-51 excels in several automated environments:

The FC-51 is an ideal component for applications that require basic, close-range detection. While it is not the right tool for precise distance measurement, it provides a simple and proven method for detecting the presence or absence of an object.

Disclaimer: Specifications may vary slightly between manufacturers. Always test your specific module with a multimeter before integrating into a final design.

2cm to 30cm (Adjustable via onboard potentiometer) Detection Angle: 35°

Mounted on the front or sides of wheeled robots to prevent collisions. Use the same pinout but connect VCC to 3

The FC-51 sensor module is designed for simplicity and reliability. Below are the core electrical and mechanical specifications: 3.3V to 5V DC Operating Current: ≥is greater than or equal to

However, some variants (or if you modify the comparator circuitry) can invert this behavior. Always test with an LED and resistor first.
