Module instructions
1. The photoresistor module is sensitive to ambient light and is generally used to detect the brightness of the light in the surrounding environment, triggering the microcontroller or relay module, etc.;
2. When the brightness of the ambient light does not reach the set threshold, the DO end outputs a high level. When the brightness of the external ambient light exceeds the set threshold, the DO end outputs a low level;
3. 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 brightness of the ambient light;
4. The DO output end can directly drive the relay module of our store, thereby forming a light-controlled switch
