20mm LDR Light Dependent Resistor

20mm LDR Light Dependent Resistor 

The 20mm LDR (Light Dependent Resistor), also called a photoresistor, is a light-sensitive electronic component whose resistance changes depending on the amount of light falling on its surface. When light intensity increases, the resistance decreases, and when light intensity decreases, the resistance increases.
This 20mm type features a large sensing area, providing higher sensitivity and more accurate light detection compared to smaller LDRs, making it suitable for outdoor and industrial applications.
