Product Description:

The photosensitive resistance module to the ambient light is the most sensitive, generally used to detect the surrounding environment of the brightness of the light, trigger SCM or relay module, etc. A module in ambient light brightness cannot reach the set threshold, DO end output high level, when an external environment light brightness than setting a threshold value, DO end output a low level.DO output port can be directly connected with the single-chip microcomputer, through the single-chip microcomputer to detect high and low levels, thus to the testing environment, light intensity change DO output end can directly drive the relay module, which can form a light-operated switch.
