Module for use
  Photosensitive resistor module most sensitive to ambient light, generally used to detect the brightness of ambient light, triggering microcontroller or relay modules;
  When the brightness of ambient light module can not reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO end output low;
  DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light to change;
  DO output of the relay module can directly drive the shop, which can be composed of a light control switch
