Fc 51 Ir Sensor Datasheet <HD × 720p>
Illuminates only when an object reflects enough IR light to trigger the output threshold. If this LED is on, the OUT pin is driving a LOW signal. Working Principle and Physics
This article serves as an exhaustive and application guide. We will dissect every parameter, explore circuit diagrams, provide code examples (Arduino), and answer frequently asked questions.
The FC-51 module is designed for simplicity and low power consumption. Below are the absolute maximum ratings and typical operating characteristics. Electrical Characteristics 3.3V to 5V DC Operating Current: ≥is greater than or equal to Fc 51 Ir Sensor Datasheet
If the reflected signal strength exceeds the threshold, the LM393 trips, turning on the onboard indicator LED and pulling the OUT pin LOW (0V) . When the path is clear, the OUT pin remains HIGH (VCC) via an internal pull-up resistor. Important Limitation: Surface Color Reflection
Below are the in-depth technical specifications, pinout architecture, and critical operating limitations mapped directly from its standard industrial datasheet footprint. 📊 Core Technical Specifications Illuminates only when an object reflects enough IR
Note: The actual detection range varies based on the object's color and material. Reflective, light-colored surfaces are detected at greater distances than dull, dark surfaces. Pin Configuration (Pinout)

We will dissect every parameter, explore circuit diagrams,
The FC-51 is an analog/digital infrared (IR) sensor module designed for short-range obstacle detection (2 cm to 30 cm). Unlike Sharp GP2Y0 series sensors (which give analog distance values), the FC-51 typically outputs a simple (HIGH/LOW) when an object is within a preset threshold.
The is a workhorse of the hobby electronics world. Its datasheet reveals a simple, robust, and cost-effective solution for digital proximity and obstacle detection. With an adjustable range up to 30 cm, TTL-compatible output, and low power consumption, it is ideal for beginners and experts alike.
Keep ambient IR low, adjust the potentiometer for your target reflectivity, and always confirm the pinout before powering up.
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.
