A Light Dependent Resistor (LDR), also known as a photoresistor or photoconductor, is a light-sensitive electronic component whose resistance decreases as the intensity of light increases. The 20mm size refers to the diameter of the LDR's sensing surface, making it suitable for applications requiring a larger area for light detection.
