LDR an acronym for light dependent resistor is a resistor whose value varies with the amount of light falling on it. It is used as a sensor to detect the light conditions in the surrounding atmosphere. The resistance of the LDR is very high of the order of Mega ohms in absence of light and it drops to a few hundred ohms or even lower in the presence of light.
