Datasheet Hot !!hot!!: Fc 51 Ir Sensor

While both use IR light, they are optimized for different tasks. Here is a comparison:

The most frequent cause of a scorching hot FC-51 sensor is swapping the and GND pins. While both use IR light, they are optimized

: The most common cause of heat is reversing the VCC and GND pins. Ensure VCC is connected to positive and GND to negative. While both use IR light

Powering the module backward causes a dead short circuit through the LM393 IC and the protective/indicator diodes.
