Light Sensitive Module

This module is sensitive to the light, usually used for detecting the ambient brightness and light intensity. When there is no light or the light intensity can not reach the value, digital out outputs high level. When light intensity over than the value, the module digital out outputs low level. The module digital output can directly connected with the micro-controller, use micro-controller detect high or low level, so that can detect the environmental light intensity change. This module can be used for drive a relay module directly or any micro-controller.
