About this product
The EKPSMD3528 is a cadmium-free ambient light sensor (LDR) in a 3528 SMD package with an analog output. Its spectral response from 450 to 1050 nm is close to the human eye's photopic curve, so it can replace CdS photocells in display backlight control, brightness sensing and other ambient light projects.

How do I read this sensor with an Arduino?
Build a voltage divider with a fixed resistor and the sensor, then read the midpoint on an analog input such as A0. As light increases, the sensor's resistance drops and the analog reading changes. Choose the fixed resistor based on the light range you need to measure.
How does it differ from a CdS photocell?
The listing describes it as a cadmium-free, RoHS-compliant replacement for CdS photocells, with a spectral response close to the human eye. It works in the same kind of voltage divider circuit with an analog reading.
