About this product
A light sensor module built around the GL5528 light-dependent resistor (LDR). Its resistance drops as light intensity rises, and the module provides both an analog output and a digital output with adjustable sensitivity. It is commonly used for day/night detection, automatic street lighting and home light automation projects.
