Instructions:
xa0
1. The photosensitive resistance module is most sensitive to the ambient light. It is usually used to detect the brightness of the light in the surrounding environment and trigger the microcontroller or relay module;
2, the module in the ambient light brightness can not reach the set threshold, DO end output high level, when the ambient light brightness exceeds the set threshold, DO end output low level;
3, DO output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, so as to detect the environment light brightness changes;
4, DO output can directly drive the relay module, which can form a light control switch.
5, small analog output AO can be connected with the AD module through the AD conversion, can obtain more accurate numerical environmental light.
