Fc 51 Ir Sensor Datasheet Jun 2026
Q: What is the detection range of the FC-51 IR sensor? A: The detection range of the FC-51 IR sensor is adjustable, ranging from 2cm to 30cm.
Detection range is highly dependent on the object's reflectivity. It excels with white or light-colored surfaces but may fail to detect black or IR-absorbent materials.

I'll follow the search plan outlined in the system prompt. search results provide a variety of sources. I need to open the most relevant ones to gather comprehensive information for the article. I'll open the results that seem to contain datasheets, specifications, pinouts, wiring diagrams, and application examples. have gathered information from various sources. Now I need to write a comprehensive article. I'll structure it with an introduction, technical specifications, pinout and wiring, calibration, comparison with other modules, example projects, and a conclusion. I'll cite the sources appropriately. FC-51 is a very popular, low-cost digital sensor commonly used for obstacle detection and line following in robotics. While finding a single, "official" datasheet for this generic module is challenging, the information is consistent across many manufacturers. This article collects all the key specifications, pinouts, and application notes into one comprehensive guide.
The reflected IR light is captured by the onboard IR receiver (a black photodiode). Q: What is the detection range of the FC-51 IR sensor
Works identically to Raspberry Pi. Use 3.3V pin. The ESP32’s GPIO interrupts work well with the FC-51 for edge-triggered detection.
Lights up immediately when the module receives stable VCC and GND.
I can provide custom code, wiring diagrams, or troubleshooting tips tailored to your specific setup! Share public link It excels with white or light-colored surfaces but
The infrared photodiode (receiver) detects the reflected IR light. The resistance of the photodiode drops as the intensity of the received IR light increases.
3.0V to 6.0V DC (Typically used at 3.3V or 5V). Current Consumption: ~23 mA at 3.3V. ~43 mA at 5.0V.
