Stair movement sensor

["Benfield, John \(Penta\)" <john.benfield-eds@xxxxxxx>]

Hi,

Can someone point me in the right direction. Someone on this list has
played with some movement sensors that can be fitted underneath stair
treads to detect that someone is walking up the stairs. I've looked
through the archive but can't find the posts. Who was it and did it
work?
