    Hi!

    I have a motion detected lamp in the garden.
    I want to hijack the motion detector and connect it to my network.

    What hardware can i use to connect and read if there is motion?

    I guess its some sort of current sensor, because i cant direct connect it to Arduino since voltage is to high.

        Yea, but i guess it will register motion during daytime?

        Any ideas?

            You can use an optocoupler, I have done so to read an 12V signal from my alarm system. Check CNY17 for example.
