Photosensitive resistance module has the most sensitive ambient light, generally used for detecting environment immediate of the brightness of the module light, trigger smc or relay, etc.
Brightness of ambient light module can not reach the threshold of setting, do exit end of high-level, when light brightness of the external environment of the development of threshold, only to stop output low level.
Output port can be directly connects to the single-chip microcomputer, through the single-chip microcomputer for detecting level up and down, so the change in intensity of the light of the test environment.
End of output can directly drive the relay module, which can form a light switch – operated.
