For those integrating the FC-51 into time-critical applications (e.g., high-speed object counting), the following timing parameters are important: Fc 51 Ir Sensor Datasheet

The FC-51's 3.3V compatibility makes it a great choice for the Raspberry Pi ecosystem. | Parameter | Value / Range | | :--- | :--- | | | 3

If the sensor fails to detect close objects, turn the potentiometer clockwise to increase sensitivity. Verify that your power supply provides a steady 3.3V to 5V. The FC-51 is an analog/digital infrared (IR) sensor

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.

Sunlight and strong incandescent bulbs emit heavy infrared radiation. Operating the FC-51 under direct sunlight can flood the photodiode, triggering false positives. 6. Microcontroller Integration: Arduino Example
