Is the resistance of a LDR affected by temperature?

Nearly cakesy -Ohm proved that current is proportional to potential difference providing temperature remains constant. So a change in temperature will affect the resistance of any electrical conductor. The movement of molecules as a conductor heats up usually increases its resistance. However some semi conductors behave the opposite way ( they have a negative temperature coefficient) as they are used in thermistors. So your LDR may well be affected by changes in temperature as well as by changes in light – you will have to look at the manufacturer’s specification to find out ( usually gives the optimum operating temperatures – or try developing your own experiment to find out.
