About LM393 Optical Photosensitive LDR Light Sensor Module For Arduino Shield DC 3-5V

Description:

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 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.
