Fc 51 Ir Sensor Datasheet Online

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

By referencing this , you now have the complete technical picture: pinouts, voltage limits, range adjustment, code examples, and troubleshooting. Whether you’re building a line-following robot, a contactless switch, or a factory counter, the FC-51 offers a straightforward “detect or not detect” solution that integrates with almost any microcontroller.
