12mm GL12528 Light Sensitive Photoresistor LDR (2Pcs)

The 12mm GL12528 Light Sensitive Photoresistor LDR exhibits a change in resistance corresponding to variations in ambient light exposure. When the light intensity on the sensor increases, the resistance across its two leads decreases. This Light Dependent Resistor, commonly known as an LDR, serves as a crucial component in light-sensing devices, whether for automatic outdoor light ON/OFF switches or indoor automatic light controls. Notably, the 12mm LDR or photoresistor sensor functions effectively in both illuminated and dim environments, making it highly versatile.

Featuring two Cadmium Sulphide PhotoConductive Cells with spectral responses similar to the human eye, this product demonstrates a decrease in cell resistance with rising light intensity. Its applications span a wide range, including smoke detection, automatic lighting control, batch counting, and burglar alarm systems. Below are some notable applications:
