Use sensitive photoresistor sensor 2. Working voltage\r\n3.3V-5V 3. Comparator output, clean signal, good waveform, strong driving\r\nability, exceeding 15mA. 4. Equipped with adjustable potentiometer to adjust\r\nthe brightness of the detected light. 5. Output form: DO digital switch output\r\n(0 and 1) and AO analog voltage output. 6. Equipped with fixing bolt holes for\r\neasy installation. 7. Use wide voltage LM393 comparator. 8. Small board PCB\r\nsize: 32mm x 14mm. Module usage instructions: 1. The photoresistor module is\r\nmost sensitive to ambient light and is generally used to detect the brightness\r\nof the ambient light and trigger the microcontroller or relay module; 2. When\r\nthe ambient light brightness does not reach the set threshold, the DO end\r\noutputs a high level. When the ambient light brightness exceeds the set\r\nthreshold, the DO end outputs a low level; 3. The DO output end can be\r\ndirectly connected to the microcontroller, and the high and low levels are\r\ndetected by the microcontroller to detect the change in the ambient light\r\nbrightness; 4. The DO output end can directly drive the relay module of our\r\nstore, thereby forming a light-controlled switch. 5. The analog output AO of\r\nthe small board can be connected to the AD module. Through AD conversion, a\r\nmore accurate value of the ambient light intensity can be obtained.\r\nApplication: Light brightness detection, light brightness sensor, smart car\r\nlight-seeking module.
