Thank you for your help.
Unfortunately I am not an electronics wizard, I have done basic wiring about the house, but all simple lights to electric type of thing.
I purchased this sensor module on the assumption that once the sensor is triggered it would simply allow the flow of electric up the chain, in this case to the LED transformer, providing electric for the LEDs. To an extent something is working, because they come on, and stay on, the sensor appears to have no say in the matter.
There are two adjustors on the sensor, one for LUX, i.e. what the ambient light should be before the sensor starts working and TIME, how long the light goes out.
Do you have a multi-meter? That diagram leaves alot to be desired. I assume that the terminal marked "load" is the one that is switched. Something like the LED's recieve power on one side and the otherside (load) is switched to complete the path to turn them on or off.
With a multi-meter you could deduce which pins are what and where the switch part is and then make sure you connect the LEDs to it correctly.
Can you send pictures of the LED cable or how you have it hooked up?
Or you could make a simple drawing in MS. paint or something else that comes with Windoze.
My problem is the diagram above was everything I was given, so I am only working on the basis that the LED transformer requires power in and out, and that the sensor Load is providing power in.
As to if the LEDs are able to switch, well I assumed this was down to the sensor?
