Good afternoon All About Circuits,

Working with motion detectors to activate LED displays. Have worked with
the Quorum G4567 but I get a lot a false signals and other problems. Found the Honeywell IS215t, which is in the same price range as the G4567 is a bit more reliable and is designed in the USA.

Tried using the signal from IS215t as a switch as in

but while one of the setups did provide on/off operation it was not as expected.

So tried using the signal to operate a transistor that would close a circuit as in
http://www.allenpitts.com/electronics/IS215T/Honeywell_IS215T_c.gif
Unfortunatley this did not work at all.

The idea is to substitute a 5 or 12 volt relay for the LED so the relay would operate the other devices, in this case, a LED display.

Any ideas?

Thanks.

Hello,

Do you have the datasheet of this honywell part?
This would give us some insight into the part, so we can give a good advice.

Good afternoon Bertus,

Sorry. I posted the data sheet on my web site but forgot to include the
URL.

Thanks.

PS When I get the IS215T to turn a simple LED circuit on and off the next
will be to get the IS215T to operate a circuit that will keep the relay
on for longer than the 'on time' of the alarm which is a couple of seconds.
Would not a 555 timer be a good for this application?
