Hi Marcus,
Under a previous topic (occupancy detection) I was looking at using
these 'Pulsor' pressure/strain sensors to detect occupancy , hoping they
might detect someone even when asleep on the sofa. But I think they
report 'change' rather than any steady load state so I didn't go any
further. I was still interested for some entry exit type light
triggering or even for my stair treads.
They may well work well for you in this application though. I may still
get some and have a play.
