FSR - the best bed occupancy sensor

Perhaps, though I’m not sure how decompression would affect the weight, but perhaps it affects weight distribution. 25 min also seem long, but I don’t have a memory foam mattress.

I definitely see this with my memory foam mattress.

This graph is pressure experience by the FSR, but you can just think of it as the inverse of resistance. So for my setup, the resistance sky rockets right when I get out of bed, then decreases over time and levels out.

My theory is that the mattress rebounds up when you get out of bed (decreasing the weight on the FSR), then increases its weight on the sensor as the mattress fully relaxes.
