    hi John

    Not sure what these have to do with your strings of LEDS ???

    you have linked to a PIR motion detector
    Did you were the data given ?
    Item Introduction:

    •The sensitivity and holding time can be adjusted
    •Working Voltage Range: DC 4.5V- 20V
    •Current drain:<60uA
    •Voltage Output: High/Low level signal:3.3V TTL output
    •Detection distance: 3--7M(can be adjusted)
    •Detection range: <140°
    •Delay time: 5-200S(can be adjusted, default 5s +-3%)
    •Blockade time: 2.5 S (default)
    •Trigger: L: Non-repeatable trigger? H: Repeat Trigger (default)
    •Trigger Method: L unrepeatable trigger / H repeatable trigger
    •Work temperature:-20-+80°C

    see the hilited line .... these supply a TTL output to feed in to Logic IC's
    You are not going to control LED strings directly from these

    What are you trying to achieve ??

    Hi Dave, I just read about or now know that i cant just use these to turn on some leds. I thought that these had like a relay in them to turn on stuff.But i found a small cir. for them.
    The cir is only about 6 parts so I'll have to build that to go alone with it.
    Darn, i thought i could just use the pir sensor by itself.
    Tks for the reply though
