The first X10 I/R motion sensor that I installed has been in service at least 8 or 9 years now and is beginning to sense much less accurately. It is indoors in a fairly small space. Replacing the batteries, which were weak but still in the good on a tester, didn't help. What is the useful service life on these devices or is there some other variable I should be checking?
P.S. :D Since w're getting older I thought our body temperature might have gone down. But we checked that and it's still OK! ;D

8 or 9 years seems to be a good life for an inexpensive sensor but with no moving parts I wouldn't know. I hope mine last forever. ;)
I also don't imagine there is any way for a layman to get a scientifically definitive evaluation of the sensitivity loss a sensor might have.
That said, I'm looking forward to the responses to your problem from those that have worked with sensors over a period of time.
...Since we're getting older I thought our body temperature might have gone down...
Hey just because we might be getting older doesn't mean we're can't still be "hot". ;D

For my flood light motion sensor (PR511), what dies, is the plastic lens. Apparently, is it not UV resistant, and will eventually just rot away.
