Equipped with adjustable potentiometer to adjust the brightness of the detected light.\n5. Output form: DO digital switch output (0 and 1) and AO analog voltage output.\n6. Equipped with fixing bolt holes for easy installation.\n7. Use wide voltage LM393 comparator.\n8. Small board PCB size: 32mm x 14mm.\n\nModule usage instructions:\n1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of the ambient light and trigger the microcontroller or relay module;\n\n2. When the ambient light brightness does not reach the set threshold, the DO end outputs a high level. When the ambient light brightness exceeds the set threshold, the DO end outputs a low level;\n\n3. The DO output end can be directly connected to the microcontroller, and the high and low levels are detected by the microcontroller to detect the change in the ambient light brightness;\n\n4. The DO output end can directly drive the relay module of our store, thereby forming a light-controlled switch.\n\n5.
