8mm LDR Light Dependent Resistor

8mm LDR Light Dependent Resistor 

The 8mm LDR Light Dependent Resistor is a light-sensitive device that changes its resistance based on the intensity of the light incident on its surface. With an 8mm photosensitive area, it offers a good balance between sensitivity and compactness, making it ideal for a variety of light detection and control applications.

In bright light, the resistance of the LDR decreases, allowing more current to pass through, while in darkness, the resistance increases sharply — a property that can be effectively used for automatic light detection systems.
