5mm LDR Light Dependent Resistor

5mm LDR Light Dependent Resistor 

The 5mm LDR (Light Dependent Resistor), also known as a photoresistor, is a passive electronic component that changes its resistance based on the light intensity falling on its surface. It has a compact 5mm light-sensitive area, making it suitable for small-scale or embedded light-sensing applications where space is limited.

When exposed to light, its resistance decreases; in darkness, its resistance increases. This property makes it ideal for light-sensing and automatic control applications.
