The Digital LDR Module is used to detect the presence of light - measuring the intensity of light. The output of the module goes high in the presence of light, and it becomes low in the absence of light. The sensitivity of signal detection can be adjusted using the potentiometer.

You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is the digital output, so you will know is the light present and decide what to do with it.
