Hello AAC forum,
Looking for a circuit or a kit that will start a timer on a relay for ten to twenty seconds.
The timer would be fired by a +3 volt signal from a PIR sensor (motion detector).

Have found several kits

Velleman has several kits but they are all 12v.
Would prefer 5 to 9 volt since that is the voltage of
load on the relay.
Thanks.
