12mm LDR Light Dependent Resistor

12mm LDR Light Dependent Resistor 

The 12mm LDR (Light Dependent Resistor), also known as a photoresistor, is a light-sensitive component whose resistance changes with the intensity of light falling on it. It exhibits high resistance in darkness and low resistance in bright light, making it ideal for light sensing and automatic control applications.

The larger 12mm light-sensitive surface allows for improved sensitivity and faster response to changes in ambient light levels compared to smaller LDRs.
