: Look for solder bridges or stray wires touching between the pins on the sensor board. FC-51 IR Sensor Datasheet Summary Sensor output stuck LOW (always detects)

The LM393 chip becomes burning hot within seconds of applying power. If left connected, it will permanently destroy the IC. 2. Overvoltage (Exceeding 5V DC) If left connected, it will permanently destroy the IC

Sensor works perfectly for 5 minutes, then constantly detects obstacle.

Based on typical FC-51 datasheet information , the module consists of an IR emitter (transmitter) and an IR receiver (photodiode) paired with an LM393 comparator chip for digital output. 3.0V – 6.0V DC

Includes a Power LED (always on when powered) and a Signal LED that lights up only when an object is detected.
