If you need to measure light levels, please select an analog output light sensor.\u003cbr\u003e\u003cbr\u003e✅【Correct Usage Steps】\u003cbr\u003e\u003cbr\u003eWiring: Connect VCC to 3.3V or 5V positive, GND to ground, DO to a digital input pin on your board.\u003cbr\u003e\u003cbr\u003eAdjustment: After powering on, use a small screwdriver to turn the blue potentiometer under your target lighting to set the trigger point.\u003cbr\u003e\u003cbr\u003eReading: Read the state of the connected digital pin in your code to determine the light condition.\u003cbr\u003e\u003cbr\u003e⚠️【Common Misconceptions】\u003cbr\u003e\u003cbr\u003eDo not confuse it with analog light intensity sensors or PIR motion sensors.
