Fc 51 Ir Sensor Datasheet !!exclusive!! [ INSTANT ✮ ]

The FC-51 is a highly popular, low-cost infrared (IR) obstacle avoidance sensor widely used in robotics, automation, and Arduino projects. It provides a simple digital output whenever an object enters its detection range.

This article serves as a comprehensive datasheet and technical guide for the FC-51 IR sensor module, covering its technical specifications, pin configuration, internal working mechanism, schematic layout, and practical interfacing with microcontrollers like Arduino. Technical Specifications

The FC-51 IR sensor has a wide range of applications, including:

void loop() int irSensorValue = digitalRead(irSensorPin); if (irSensorValue == HIGH) Serial.println("Obstacle detected!"); else Serial.println("No obstacle detected."); Fc 51 Ir Sensor Datasheet

Adjust until the green indicator LED just lights up when the object is present and turns off when the object is removed. Interfacing with Microcontrollers (Arduino Example)

Ground connection. Connect this to the common system ground.

: Digital output pin. It outputs a LOW signal when an obstacle is detected and HIGH when the path is clear. How It Works The FC-51 is a highly popular, low-cost infrared

The is a cost-effective, reliable solution for proximity detection, offering adjustable ranges up to 30cm. Its simple 3-pin interface and digital output make it perfect for integrating obstacle avoidance into various automation and robotic projects.

While the FC-51 lacks a formal, manufacturer-published datasheet (most are generic Chinese modules), the specifications and behavior outlined above are universally accepted by the maker community. It is not a precision instrument, but for , it is an unbeatable workhorse for basic proximity sensing.
