An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits. A typical LDR Photoresistor is a resistor which made of semi-conductor material and the conductance changes with luminance variation. The photoresistor can be manufactured with different figures and illuminated area based on this characteristic. Photoresistor is widely used for many applications such as toys, lamps, camera, automatic lighting control, etc.
