First, adjust the 502 resistor (frequency) to find the strongest signal point. Then, adjust the 103 resistor (threshold) to set the desired triggering distance, ensuring a clear HIGH\/LOW output difference between the background and the black line.\u003cbr\u003e \u003cbr\u003e Enable (EN) Pin Usage:\u003cbr\u003e \u003cbr\u003e Default Operation: Use a jumper cap to short EN to GND.\u003cbr\u003e \u003cbr\u003e Power-Saving Mode: Remove the jumper.
