Fc 51 Ir Sensor Datasheet Hot Jun 2026

Place a 0.1µF ceramic capacitor across the VCC and GND lines close to the sensor to filter out voltage spikes.

The FC‑51 shines when you simply need to know and your operating environment is indoors or protected from direct sunlight. fc 51 ir sensor datasheet hot

Operating the sensor at 5V instead of 3.3V dramatically increases power consumption (43mA vs 23mA). While 5V is allowed, it leads to faster heating of the IR transmitter LED and the LM393 chip. B. High Potentiometer Sensitivity Place a 0
