WebIn dark, LDR offers very high resistance as high as 10 Meg Ohm but it reduces to 100 Ohms or less in bright light. So LDR is an ideal light sensor for automatic lighting systems. During day time, the LDR has less resistance and current flows through it to the threshold (Pin6) and the trigger (pin2) inputs of IC.
