Fc 51 Ir Sensor | Datasheet Hot

However, by understanding the thermal physics of the LM393 and IR phototransistor, you can implement simple countermeasures: reduce voltage, duty cycle the power, calibrate while hot, or add hysteresis. For critical systems, upgrade to a thermally-compensated sensor.

Do not calibrate the potentiometer at power-up. Let the sensor run idle (with IR LED active) for 15 minutes, then adjust the blue trimmer for the desired range. This “hot calibration” ensures thermal equilibrium. 4.5. Add a Heat Sink or Airflow A tiny stick-on heatsink (8x8mm) on the LM393 can drop temperature by 8–10°C. Even a small fan (5V, 30mA) blowing over the sensor dramatically improves stability. Part 5: Comparing FC 51 to Thermally-Stable Alternatives If the “hot” problem is killing your project, consider these drop-in alternatives. fc 51 ir sensor datasheet hot
