I have a canon S3-IS connected to an alarm detector.
When someone pass in front of the detector it send 5 volts to the usb port and the camera takes a picture.
What I would like is use a intervalometor to take more than one shot.
The problem is that you have to press the shutter button to activate the script.
Is there anything I can do that will trigger a script with the remote.

Any ideas would be greatly appreciated.

Welcome !

If I understand you correctly, you do not want an intervalometer but a continually-running script that takes a photo whenever there is a signal from the alarm detector.

Something like this :-

Code: [Select]

@title Alarm detector
@param a lockout time (secs)
@default a 10
a = 1000*a
rem wait for remote switch press
do
until is_key "remote"
rem now wait for alarm detector signal after five second delay
sleep 5000
:loop
do
until is_key "remote"
shoot
sleep a
goto "loop"

The lockout time prevents retriggering until after the set time.

Somehow, you have your detector and remote switch both connected to the USB.
