Fc 51 Ir Sensor Datasheet Hot May 2026

FC-51 IR obstacle avoidance sensor

If your is getting hot , it is likely due to a wiring error, excessive voltage, or a component failure. Under normal operating conditions, this sensor should remain cool to the touch. Quick Troubleshooting for Overheating

  • Limitations:
    1. Pinout: The sensor has three pins: VCC (power supply), GND (ground), and OUT (output signal).
    2. Operating voltage: 5V
    3. Current consumption: 20mA
    4. Detection range: 2-30cm (adjustable)
    5. Output type: Digital (high/low)
    6. Response time: 500μs

    A:

    Different reflectivity. Dark surfaces absorb IR. Increase potentiometer sensitivity (turn counter-clockwise). Do this after the sensor is thermally stable. fc 51 ir sensor datasheet hot
