《使用說明》

1. the photosensitive resistance module is most sensitive to ambient light, generally used to detect brightness of ambient light, trigger MCU or relay module etc.;
2. module in the brightness of ambient light is not up to the preset threshold, the DO output high level, when the brightness of ambient light outside exceeds the preset threshold, the DO output low level;
3. the DO output can be directly connected with the MCU, the MCU to detect high level, thereby detecting the environmental light brightness change;
4. the output of the DO can directly drive the relay module, which can form a light operated switch.
