Usage
1. This module is sensitive to light, commonly used to detect ambient brightness and light intensity.
2. If there is no light or the light intensity can not reach the value, DO intensity output is high level.when light over than the value, DO the module performance is low level
3. The module digital output DO can be connected directly to the microcontroller, the use microcontroller detect high or low level, so that the environmental light intensity change can detect.
4. Can use this board digital output interface module drive relay directly DO can also use as optical switch.
5. The analog output AO connects to AD module, and it can get a more accurate light intensity value through the AD converter.
