Fc 51 Ir Sensor Datasheet — Hot

The module typically features a 3-pin male header for easy interfacing with microcontrollers like Arduino or Raspberry Pi. Go to product viewer dialog for this item.

For battery-powered or heat-sensitive projects, switch to a 5V supply and add a transistor to pulse the IR LED. Your sensor—and your fingers—will thank you. fc 51 ir sensor datasheet hot

Sensor works perfectly for 5 minutes, then constantly detects obstacle. The module typically features a 3-pin male header

The LM393 lacks hysteresis. Add a 100kΩ resistor from the output to VCC to introduce positive feedback. This reduces oscillation and thermal noise false triggers. fc 51 ir sensor datasheet hot
