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