Description
  • Photosensitive resistance module's most sensitive to ambient light commonly used to detect the environment around them
  • brightness of the light, or MCU trigger relay module, etc.;
  • The module in the environment light intensity than the set threshold, output high level DO end, when the environment light intensity more than a set threshold, the DO output low level;
  • The DO output can be directly connected to the microcontroller, through a single-chip microcomputer to detect the high and low level, thus to detect the environment light intensity change;
  • 4 the DO output can be directly driven our relay module, which can form a light-operated switch.
