LDR is one kind of photoresistor and light dependent resistor that is sensitive of light. When light falls upon it then the resistance changes. Values of the resistance of the LDR may be change over many orders of magnitude the value of the resistance falling as the level of light increases. It is not uncommon for the values of resistance of an LDR to be several Megaohms in darkness and then to fall to a few hundred ohms in bright light. With such a wide variation in resistance, LDRs are easy to use.
