How to use Photosensitive LDR Sensor Module:

• Photosensitive resistor module most sensitive to environmental light intensity is generally used to detect the ambient brightness and light intensity.
• Module light conditions or light intensity reach the set threshold, DO port output high, when the external ambient light intensity exceeds a set threshold, the module D0 output low;
• Digital output D0 directly connected to the MCU, and detect high or low TTL, thereby detecting ambient light intensity changes;
• Digital output module DO  can directly drive the relay module, which can be composed of a photoelectric switch;
• Analog output module AO and AD modules can be connected through the AD converter, you can get a more accurate light intensity value
