Fc 51 | Ir Sensor Datasheet Work

Yes, the FC-51 works from 3.3V to 5V. However, the digital output will swing between 0V and ~3.3V when powered at 3.3V. This is safe for 3.3V microcontrollers.

Triggering a count when an item passes by on a conveyor belt. Proximity Switches: Non-contact buttons for touchless interfaces. 5. Conclusion Fc 51 Ir Sensor Datasheet

The module features a 3-pin male header interface. The labels are often printed on the back of the PCB: Yes, the FC-51 works from 3
