Light Dependant Resistor

I've just pulled a solar garden light apart and the LDR is connected to the little LED board with single wires shrouded in a loose cloth type of insulation. I want to separate the LEDs from the solar panel. The LEDs being inside the house, and the PV panel including LDR being outside. I was going to connect the two with a length of figure 8 cable through a small hole in the window frame. Will this be a problem? Or does the LDR have a specfic connection need? TIA, jack

From your description, you won't be disturbing the LDR wiring - just extending the LED connection. That will work fine.

Thanks Ed, my description must be poorly. I want to extend the wiring of both. The LEDs must be inside the house, and the PV panel and LDR outside for the sunlight/ambient light. The extension will hopefully be around 2 or 3 feet, and I have some

1mm^2 figure 8 if that will be suitable, if not grossly over-engineered :) What I want to know is if there is something special about the LDR wiring. Why the baggy pyjamas? Thanks, jack

May not have anything to do with your application but I use a lot of different light dependent resistors on the gun burners I work on at work-(heaters used for -grain dyers/ houses-small flame throwers etc etc) I have found that extending the LED will be no problem as long as you use the right AWG wiring size but the LDR is sometimes a little difficult as this is susceptible to induced resistance by small wiring diameter and outside influences like eddy currents from other cables if near the cable running the LDR. Sometimes the power supply wire running to the LDR is resistor wire it self -up to 1k ohm but this is not the norm. I think it should be ok but if it don't work try using a shielded cable to connect the LDR. remember there is only a couple of milliamps running through this part of the circuit

You don't need to disturb the LDR. Unsolder the LEDs from the board. Put wires in the place the LEDs were, noting polarity. Bring the other end of the wires to the place where you want the LEDs. Solder the LEDs to a new PC board like this one:

If you must move the LDR, there is nothing special about the wiring.
