Sensor Datasheet !!link!! | Fc 51 Ir
The FC-51 is a low-cost, compact infrared sensor module designed for and line following . It emits IR light and measures the reflection from a nearby surface. The module outputs a simple digital signal (HIGH/LOW) that changes state when an object is detected within an adjustable range.
Always test your specific module’s range with your target object before finalizing your design.
Q: Can the FC-51 IR sensor be used with Arduino? A: Yes, the FC-51 IR sensor can be easily interfaced with Arduino and other microcontrollers. Fc 51 Ir Sensor Datasheet
The datasheet for the FC-51 IR sensor provides the following key specifications:
The infrared emitting tube continuously shoots out a beam of high-frequency infrared light. The FC-51 is a low-cost, compact infrared sensor
delay(50);
The FC-51 is a low-cost, highly efficient infrared (IR) obstacle avoidance sensor module widely used in robotics, automation, and DIY electronics. This module utilizes infrared reflection to detect objects within a specific range, making it an ideal choice for wheeled robots, security systems, and manufacturing line counters.

| Parameter | Value / Range | | :--- | :--- | | | 3.3V to 5V DC | | Current Consumption | 20 mA (typical), 50 mA (peak) | | Detection Distance | 2 cm to 30 cm (0.8” to 12”) | | Adjustable Range | Via onboard potentiometer | | Output Type | Digital TTL (Active LOW – 0V when object detected) | | Output Current | 15 mA (max) | | Response Time | Approximately 10 µs to 50 µs | | Field of View (FOV) | ~35 degrees | | Operating Temperature | -25°C to +85°C | | Board Dimensions | 32 mm x 14 mm x 12 mm | | Mounting Hole Pitch | 22 mm |
Detection range varies with object color and reflectivity. Black objects absorb IR and will be detected only at much closer distances (e.g., 2-5 cm), while white objects can be detected up to 30 cm.
