Thanks for the suggestions. Jane is not with it enough to push buttons. Bed alarms don't work, if she only sits up, we tried those things. I think I need a system with a beam that she would interrupt when she sits up. Thanks again for the input. I will go find this playground thing.............LEE
Other possible suggestions:
PIR sensor - motion sensor like that used on alarms - http://www.goldmine-elec-products.com/prodinfo.asp?number=G12959
- you would have to hack this, of course (just hook up to the LED)
Laser "tripwire" type sensor - something similar to this: http://www.goldmine-elec-products.com/prodinfo.asp?number=C6739;
there are also similar circuits using a phototransistor, etc. Sense the "beam break".
What you would probably want, though, is more than one of these sensors; maybe a pillow sensor, the tripwire sensor, and the PIR sensor - then set things up to eliminate potential "false positives".
Although - if I am reading your situation right (and if I am, my sincerest best wishes for your family) - a false positive will be better than missed one...
Hope this helps.
