Module instructions
1, the photosensitive resistor module is most sensitive to ambient light, generally used to detect the ambient light intensity, trigger microcontroller or relay module;
2. When the brightness of the ambient light reaches the set threshold, the DO output will be high. When the ambient light intensity exceeds the set threshold, the DO output will be low.
3, DO output can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which detect the ambient light brightness changes;
4, DO output can be directly driven shop relay module, which can form a light control switch.

5, small board analog output AO can be connected with the AD module, through the AD conversion, you can get more accurate ambient light intensity values;
