About this product
A light-sensing module built around a GL5528 photoresistor (LDR) and an LM393 comparator. The LDR's resistance drops as light increases, and the comparator produces a digital D0 output that switches when the light crosses a threshold set by an on-board screw adjustment. It suits dusk-activated lights, light detection and simple light-beam alarms.

What does the D0 pin do?
D0 goes high when the light level falls below the set threshold (dark) and goes low when the light is above it.
How do I set the light threshold?
Turn the on-board adjustment screw while observing D0 until it switches at the light level you want. Then connect D0 to a digital input of your microcontroller.
