The module emits infrared light via the . If an object is within range, the light reflects back to the receiver LED (phototransistor). The LM393 comparator compares the received signal against a threshold set by the onboard potentiometer . When an obstacle is detected, the green indicator LED lights up and the OUT pin pulls LOW .
